Spotify doesn’t scale, so the interface is tiny.Images being edited in 100% zoom are shown without desktop scaling, so no serious editing can be done as the exported image is larger. Gimp doesn’t scale, so the interface is tiny with microscopic icons.I ran into the following problems and none of the solutions that Google spat out worked: Unfortunately desktop scaling support still seems to be incomplete. Run these commands to modify grub and reboot: sudo update-grub2 & sudo update-initramfs -u -k all GRUB_CMDLINE_LINUX_DEFAULT="radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1 amdgpu.dc=1 amdgpu.dpm=1 amdgpu.modeset=1" The commands are straight from my previous article.Įdit the /etc/default/grub file: sudo mcedit /etc/default/grubĪdd these lines: GRUB_GFXMODE=1920x1080x32

We have to add a few parameters to Grub to make the amdgpu driver work.

Now update grup by issuing the following command: sudo update-initramfs -uīe aware that if you reboot now, you might end up in a very low desktop resolution. …and add the following line at the end: blacklist radeon To disable radeon, you have to edit /etc/modprobe.d/nf: sudo mcedit /etc/default/grub … you’ll see that you have two kernel modules available: radeon and amdgpu. If you run the following command… lspci -k | grep -EA3 'VGA|3D|Display' To tell the truth, I’m not sure if this step is really necessary, so if you succeed with only step one and three, please tell me in a comment, so I can update the article. However if you see “radeon” there, you are still on the open source driver and need to take a few more steps. If you see “amdgpu” there, your are ready, no need to continue with this article. Issue the following command to see if the driver is active: lshw -c video Sudo ppa-purge ppa:oibaf/graphics-drivers

If you ever need to get rid of it, use these commands: sudo apt install ppa-purge

I found out in this article that you can use the official drivers by adding a PPA with the following commands: sudo add-apt-repository ppa:oibaf/graphics-drivers Step one: Use the official amdgpu driver from a third-party PPA repository At the moment 125% desktop scaling seems to work perfectly without flickering and youtube didn’t froze my computer either. So, after some digging I found the solution to make everything work. Another thing is that using the monitor in 1440p seems to be a bit more blurry than with Ubuntu 18.04 with the amdgpu-pro drivers.ĭon’t worry, we are coming to a happy ending soon ? Also, the official AMD drivers are not yet available, so I’m stuck with the open source radeon driver shipped with the distro, which tends to freeze my computer when watching youtube videos. After a quick reinstall, I sadly had to conclude that the flickering text problem still persists. This way there was no flickering, the content was sized okayish, but the image was just not as crisp as on native 4K.įast forward about 7 months and Ubuntu 20.04 arrives. This rendered the user experience totally unacceptable, so after weeks of experimenting I had to settle to using the 4K monitor on 1440p resolution. I tried a bunch of Ubuntu versions and even other distributions, but when desktop scaling was even available, I always had some flickering text when typing something as if the window manager tried to redraw the windows after each keystroke. This works out of the box on Windows 10, but was always problematic on Linux. The sensible thing to do is to turn desktop scaling to 125% or 150% to stay on the native resolution and still enjoy crisp and appropriately sized text. Unfortunately my eyes are getting a bit old, so using Windows or Linux in native 4K resolution is out of the question. I also have a LG 32UK550 4K UHD VA FreeSync HDR LED Monitor and do want to enjoy the extra crisp resolution. I’ll probably stick with it for a few more years. I have an ASUS Radeon R9 390X STRIX OC 8GB GDDR5 (STRIX-R9390X-DC3OC-8GD5-GAMING) video card which is getting quite old in 2020 but still is quite perfect for my huge gaming backlog.
