[Q] change display resolution/visible screen - Ubuntu Touch Q&A, Help & Troubleshooting

Hello,
i want to start using ubuntu touch on my nexus 4. The problem is, the touch screen does not work on the uper part of the display (just some pixels).
I already installed Ubuntu and i really like it. The Problem is, i cant use the notification center nor the back buttons of the apps.
So, is it possible to reduce the screen resolution, that the upper part of the display is not in use anymore?
Thanks and best regards

As you haven't received any reply yet, I'd like to point you to the official Ubuntu Phone mailing list which you can subscribe to at launchpad.net/~ubuntu-phone.
If anyone can help you with this, then those are the people from the list.

[Q] Serious multitouch issue - most obvious in games

Bear with me here, this issue is kind of hard to describe. When I am playing a game that requires touch inputs from both hands, I often get bugs. It's most obvious in games that have controller-style overlays. As is normal, I am using my left thumb to tell a character to move right or left, and then I press the button on the right to jump. However, when I release my jump, I stop running. The screen no longer recognizes that my left thumb has been pressed down the whole time and should still be moving in the direction I am pressing. This happens in Bean's Quest, Chono'n'Cash, Delver, Gunman Clive, and any other game of this nature I have tried on my device.
I played some of these games just fine on my old Evo. Is anyone experiencing this issue? I experienced it on stock as well as several custom roms I have tried.
Turn off "Htc gestures" you'll find it in settings, display & gestures!
When the display senses three finger inputs it renders it touch inputs useless...run a multi-touch test app and you'll see.

Doesn't seem to have fixed my issue, I am still having problems with some two finger games. I will be using two fingers just fine, when I remove one finger from the display the first finger is no longer recognized even though it is still touching. I have to remove the first finger and press it again every time.
Do U have any type of lock screen installed. If so uninstall. Use only stock.

Appears that widgetlocker is the culprit! Is this issue documented or known, exactly? What causes it? Thanks so much for the help. I will surely miss widgetlocker.

Moving to Q&A
I encountered this recently
It seemed to get "stuck" after using multi touch gestures in-game. Tapping the game with two fingers often "unstuck" it, but overall it was extremely frustrating.
This was on an APK not designed for the phone, though
Sorry to bring back up an old thread (is 6 days even considered old?) anyway you HAVE to disable the HTC 3 touch setting gesture because it will ignore anything more than 2 (3 will only register if you swipe up or down, but sense itself registers it, nothing else).
Just made the video below as proof (forgive my foreign accent xD):
Our screen supports (at least) 10 different points (was going to try 11 but I could not get my nose on the screen with my fingers and my girlfriend is asleep).
EDIT: Two things, one: I had widgetlocker installed while I did the above video, it caused no problems. Two: the maximum number of inputs our phones can handle is 10, incase anyone was curious.
EDIT 2: While I don't have the issue with widgetlocker it seems that it is a known problem, but you don't have to disable the lock screen altogether. Go into widgetlocker settings> advanced> retain system key guard. Source: http://forum.xda-developers.com/showthread.php?t=1652038

Did you try my edit 2? The Retain System keyguard? I can assure you that I have Widgetlocker installed and I have the 10 inputs (that video was recorded with widgetlocker running).
[SOLVED!] - HTC Evo 4G LTE touch screen trouble - WidgetLocker is the problem
Retaining system keyguard in WidgetLocker worked for me! Thank you for this Racer for All. (Actually I found your YouTube video, and a link to this thread)
I was wondering why all the games I played all of a sudden stopped functioning properly (in terms of touch controls... Example: MineCraft PE, moving forward and trying to look left or right - suddenly character would stop moving.)
Sorry to dig up an old thread, but I want people to know if they have WidgetLocker (and don't want to uninstall it) just go to Settings - Advanced - Retain system keyguard - zmag

[Q] Multi touch alternative?

Hello guys. I've been following the forum for quite a while but its only now when I decided to sign up. I recently slipped my htc sensation and broke the digitizer. When I got it replaced the multitouch wasn't working and the guy who replaced the digitizer said nothing could be done to fix it. It might seem like it's not a bid deal but I really do miss my multitouch. I tried to play the new game "ingress" by google but it's pretty much impossible because it requires pinch to zoom and two finger scrolling. This is why I was asking if it was possible to assign my device a new gesture or combination of gestures so that I can zoom in and out ? I searched for apps to help me but they only seemed to work with images and not apps.

[Q] Android for disabled people with eyesight problems (LONG)

Hello.
I apologize in advance if this is not the right forum to post in, or if it's not the right site at all, but a friend whose specialty is Android led me here, and told me to post my problems here.
I am a long-time iOS user. But I am also disabled : I have 1/20th vision on my left eye and nothing on the right one. My eyes are easily blinded by light, and as such I find it painful to read text on a screen when it's black on a white background. In Windows, for instance, I change the Windows theme back to Classic Windows so I can edit the different colors that make windows, buttons, and menus so they are easier on my eyes. In OSX, I use the 'Invert Video' feature on a shortcut key, so that when I press it, the screen suddenly inverts all colors, makign it much easier on my eyes. (Sadly, it also inverts colors on pictures, but that's okay, I can live with switching back and forth if needed.) On Chrome (any OS), I use the Stylish extension to force every site's CSS to follow my own and keep backgrounds dark and text light... You get the idea. On iOS, a similar feature to the one in OSX exists, and you have to press the home button three times to switch it on or off.
If I'm posting on this forum, this is because I have questions regarding Android's features for disabled people like me.
From my understanding, and from what I briefly tried on my sister's Acer E330 (Android 4.0.4) there is no such feature. A friend with a Nexus 4 confirmed this too.
I was wondering if there was some kind of plugin, addon, extension, app or whatever that would allow me to redefine Android's interface (a theme perhaps?) or even better, some kind of 'Invert Video' feature just like on iOS. I'm asking about this because I'm considering buying a Android device since I realized I was starting to have problems with some displays used on recent iPhones, iPads, Macbooks or even on regular PC laptops like MSIs' or Samsungs'.
The problem I have has been unresolved so far as there is no way to tell what part/setting of recet LCD/LED displays make my eyes sore after about 5 minutes of use. I did a lot of research without being able to find out what caused this exactly, but a lot of people seem to have the same kind of problem while having a normal eyesight unlike I do.
So, right now, two things prevent me from being sure if I should buy a Android phone or not :
- I need to make sure the display is fine with my eyes.
- And the reason why I'm posting this here, is that I want to know if it's possible to have the same kind of feature on iOS/OSX for changing colors of the whole screen by the press of a physical button on the device several times (this seems like the best solution, as a system setting switch would be a bit painful to use. FYI I really overuse and abuse this feature because it allows me to quickly switch to a dark background on white pages, while restoring the normal colors if the next page I'm visiting has a black background.)
So there it is, again, I apologize if that wasn't the right forum or anything. I hope someone here can help me with this problem. I'm not a die-hard Apple fanboy : I just happen to use their devices because they are the simplest to work with considering my disability.
Thanks in advance.

Anyone having issues with Firefox browser?

I'm having some screen issues with Firefox. Sometimes the bottom of the screen goes black and the tabs at the top disappear. By using split screen mode I can repair this but it does seem to come back regularly. Strangely enough I can replicate this behavior by using the volume down button (wtf?) when a video is playing on a website. It seems some kind of screen resolution thing, in Firefox it's reported as 1195x747x24 but in Chrome I see 1205x753x24.
Is anyone else having these screen issues with Firefox, and am I right in thinking that it is Firefox that somehow gets the resolution wrong and that that's the cause? Why its also related to the volume button is beyond me.

I don't know the answer, sorry, but curious if you've tried the jelly (for lineage) browser? You can find the apk by searching xda if you didn't know.
I ask about that because jelly is using the system html rendering, so it may work and be very minimalist. Aside from that, and hope u don't mind my asking, why not use apps when available? I'd expect the app for netflix etc to be able to function no issues. If not, there should be support from them. But ff not playing a video properly? not sure there's much support available for that?
Have you automatic screen resolution adjustment checked or free form mode activated (as indicated by me in that thread) via adb?
(When free form was activated I realized similar behavior in free form apps)
I found out that Firefox beta doesn't have this issue, so I presume whatever it is it'll be fixed in the next release of Firefox.
Screen issue is fixed now with the update., Firefox working the way it should now.
I presume other screen issues with video playing like people have reported with vlc will also be fixed.

LG dual screen

1. Can you flip backward the screen when connected to dual screen? For vlogging using rear cameras & 2nd screen?
2. What happens when you use dual screen and mirroring your screen wirelessly or wired?
3. What happens when you connect other phones to the USB c port of dual screen?
4. Can you use double dongle connected to your phone port and dual screen port? So it's more flexible in terms of usability
5. Secondary screen support haptic feedback vibration?
6. Can you hide 2nd screen notch?
You'll have to take my answers with an understanding that a bit of it will be speculation. You see, I do not own an LG G8x Dual Screen. I do, however, own a Korean LG V50 Dual Screen, so I can provide some insight and provide you with some answers

This will not work. The Dual Screen can flip open to 360°, putting it behind the device, but two things are going to prevent you from using it like you've asked. The secondary screen, at least on the V50, shuts off when the case reaches this position. It actually stays on for most of the arc, only flicking off at about 350°, but it does render itself unusable on the back of the device. Even if this can be changed in the software of the G8x, the second problem is that in this position, the 360° opened Dual Screen, facing the rear of the device, will block the backside of the primary device, obscuring the cameras. The Dual Screen will only face the rear of the device in this 360° opened position, at which point the primary cameras will always be blocked.

It mirrors the primary display. I haven't tested what happens on any of the handful of dual screen "wide mode" compatible apps, but I would imagine it would still only show the right pane on your mirroring device. However, I do speculate that it could be possible to mirror the dual screen instead, if you could pick out which activity in the system is the begin mirroring command and then set a widget or Tasker profile to automatically initiate it. There are some system apps that do not allow you to move it over to the Dual Screen display, and the cast screen subsetting menu is one such app. However, I believe that it might be possible to cast the secondary screen instead if this were the active screen at the time that screencasting began. As far as casting both, I doubt this would every be possible. Most apps can only exist on one screen or the other at a time, per install. (There are ways to install multiple copies of an app, but they become entirely separate apps as far as the system can tell.) The screencasting service is one such app, which can, in theory, only exist on one display environment or the other. Maybe it could be possible to get two separate screencasting apps and run one on each display, but then you would need to cast to two different devices. I guess I'll go with a hard "maybe" on this one.

3. What happens when you connect other phones to the USB c port of dual screen?
Click to expand...

I will assume that nothing happens. You see, the supporting software to run the Dual Screen is preinstalled on the V50, on the primary device, and mI assume this will be the same on the G8x. The Dual Screen Settings subsetting menu is present in the system menu. The Dual Screen's Home Launcher is installed on the primary device. Connecting, say, a Galaxy s10 will likely cause nothing to happen, because the s10 would not have any software or drivers to interface with the Dual Screen Accessory.
That said, I am interested to see if my Dual Screen capable V50 will be able to interface with the G8x Dual Screen Accessory, and I will test this as soon as I get the chance.
Likewise, I'm interested to see if anyone can reverse engineer the drivers and allow the Dual Screen Accessory to be used with non-native, or non-LG devices. As soon as everyone realizes that the Dual Screen form factor is the future, and this silly foldable display hype bubble deflates, I think we'll end up with some competent developers working on the issues.

This is an interesting question. Do you mean just using a USB c female to USB c male cord, to plug the device into the dual screen, but at a distance? I don't see why not. To plug it into a splitter so that you can plug in another device? Probably unnecessary, as there is a port with some style of USB c passthrough on the case, but it might work, as long as the device isn't trying to draw a bunch of power from the device. The screen is powered through this port, and you could easily exceed the power output limits of this port.
And if you're asking about the possibility of using some kind of a splitter to try to Daisy Chain a couple of dual Screen Accessories to a single primary G8x device, that's crazy enough that it just might work, if you can figure out the power issue.

The Dual Screen Accessory does not have a Haiti motor of it's own, but the haptics work from the primary device when you are working on the dual display.

Hide, Probably, to some extent. The V50 insides
Includes the option to hide it in the LG apps and preinstalled apps, but it doesn't usually work on third party apps. I haven't sought a third party "notch hiding" app, because frankly, the notch doesn't bug me at all. And on the V50, it is much more pronounced. But there's no way to "turn it off" even in the Dual Screen, where it is entirely non-functional. The notch exists because of a lack of pixels being there at all. The Dies that they use for the manufacture of the screen are responsible for the notch, which LG Included "unnecessarily" in the G8x so that they could simply have their two screens come from the same supplier, same batch, so that they will have Identical specs and color science. There's no way to turn the pixels there back on or anything, but there might be something you can do about turning the whole top strip of the phone into a dark, notch hiding, fuax bezel or whatever. I dunno, if the notch is a problem for you, I don't know what to tell you. I'd guess that you've not had a device with a notch before. Because they really aren't a big deal. Especially not these little teardrops.
Of course, individual milage may vary. But if the notch is a turn off for you, don't let the fear of the notch dissuade to from your interest in this device. What LG is doing in the space is revolutionary. Be the first you know to try it, and you'll see exactly why I think Multi Display Tech is the future of smartphones.
Your answers are really fantastic!
1. Can you flip backward the screen when connected to dual screen? For vlogging using rear cameras & 2nd screen?
This question is for g8x reversible type c which is located at perfect middle bottom. I mean, like put it down lying backward, for vlogging purpose,
4. Can you use double dongle connected to your phone port and dual screen port? So it's more flexible in terms of usability
Imagine putting both dual screen closer, less gap, bezelless, same height level, to run as one big tablet mode. Using cables, which can be hidden underneath / inside the case
8. Have you got the latest update to run one app on both screen as a whole big continuing screen?
LG stock apps are quite flexible with dpi, they are adaptive and scale well with tablet mode UI
Can you force it via developer menu to make it work? Big tablet modes for all apps
9. Do you know some dedicated apps for dual screen? Other than naver whale browser and some 5g demo apps
It seems like LG uses different SDK & API compared to Asus twinview. So asphalt 9 & some dual screen games aren't compatible with LG dual screen
GCam+gphotos?
gdocs open documents + list?
Dual window chrome?
10. Can you find some system apps that could possibly refer to dual screen feature?
I would be very interested if V50 is compatible with the new G8X dual screen. I was able to get the V50 on the cheap in US and G8X will be released soon here in Europe.

This is only physical compatibility. I have found Korean video where one user tests exactly that and it doesn't work.
Does anybody have any idea about whether the dual screen would work with the regular G8? It looks like there's enough open space for the fingerprint scanner on the back. If it's a software issue, could the apps be sideloaded?

Someone needs to try change 'enable force resizeable all apps' in developer option for that
I was able to do it in chrome. If you use chrome in portrait node and enable "wide view" mode, chrome splits across both screens and the keyboard is split in half with one half on each screen.

Which apps work in Split view mode? Or is it only Chrome?
And if you enable force resizeable all apps' in developer option (suggested by harysviewty), does that enable all apps to work in split view?

No unfortunately this doesn't allow you to run apps in wide view, only chrome seems to suuport this festure as of right now.
