Hello good people,
I have a unique problem for which I found no other info online, where my built-in display glitches and is unusable, while my external display is completely fine. I uploaded a short demonstration here https://imgur.com/a/kkNy6Zj.
The laptop is a Dell XPS 15 7590 with GTX 1650 with FullHD IPS display (not the OLED version). It came with Windows preinstalled and the screen was fine then so I suppose it is not a hardware issue. This issue is the same in Live USB with both Ubuntu 19.10 and 18.4.03 LTS Driver is nvidia-driver-435 installed via Software & Updates app. BIOS is updated (through Windows) to 1.3.3, SecureBoot disabled and set to AHCI mode. The DM currently running is LightDM I don’t actually know why anymore.
Ubuntu 19.10 Live USB without safe graphics mode is pretty much the same as my setup. With safe graphics it successfully boots and the flickering stops! However my external monitor does not work and is not even detected. When I try to boot my system with nomodeset (written during boot to the grub line after “quiet splash”), only a black screen shows and I cant start LightDM with tty terminal.
I have tried a lot of things past few days, but I don’t remember what things I did and what I reverted, so I hope the included log clears it up. What I am pretty sure didn’t work is:
- nvidia-driver-440 with apt install from graphics-drivers PPA
- nvidia-driver-430 from Software & Update app
- nouveau drivers from Software & Update app
- installing newest PopOS (same screen flickering)
I tried to configure the displays with “nvidia-settings”, but in the X Server Display Configuration when I click the Advanced button it shows no new options.
The GPU is apparently working fine though, I can run “nvidia-settings” and “nvidia-smi” no problem and even Tensorflow can run on the GPU.
Thank you for reading, if I should add more info, please let me know.
