I have upgraded from Ubuntu 19.10 to 20.04, and now I have a problem with my graphics rendering (strange squares on background and font problems). I use the i915 driver. Graphics card: Skylake GT2 HD Graphics 520. I tried to reinstall GNOME shell and Xorg server. Nothing helped. Also Chrome browser breaks on most of pages.
recently I upgraded from 19.10 to 20.04 LTS. Everything is working fine except some minor display issue. Display resolution if good but every time I turn on my computer or restart it, there is square green patches or vertical green lines over the wallpaper. Also, the moment I change the wallpaper it disappears. I don't what the exact issue is? I am using HP notebook. Below I have attached what it looks like.
I have recently installed four computers with Linux. Each one has different monitors, refresh rates, versions, etc. The only constant in all four is the processor with the integrated graphics. Here is a screenshot that I was able to take.
AMD doesn't have official drivers for Linux for this particular processor and I'm not entirely sure about where to go from here. Has anybody else had issues with this?
I have been conducting tests, and I see there is no issue at all with a fresh installation of Ubuntu 18.04.3. I still have a little more testing to do, but I reckon it will start giving me issues as soon as I update my drivers in 18.04.
It turns out I was exactly right. It seems like there are issues with the current kernel with this specific AMD processor. We just ordered a few Nvidia graphics cards because we need to run programs that require specific kernels and we can't afford to waste any more time on this issue. If anybody needs a quick fix and doesn't necessarily care about which kernel version they are using, I found that version 5.0.0-23 works without any issues.
I installed Ubuntu 18.04 a day ago. It works perfectly but graphics is a problem; I see screen flickering where there are system or JS overlays and blurred text.
What can I do - my graphics are based on intel chip
Running sudo lshw -c display
I get

Is it possible to set the GPU fan speed using the default free ati driver?
My card (X1900) was deprecated in the fglrx drivers a while back.
The free drivers seem to work with 3D, Compiz and such, but running graphics intensive programs makes my GPU heat up and produce artifacts, while the GPU fan never seems to increase. (When set to 100% in Windows it makes a massively louder noise.)
