Hi,
I have a Radeon R9 270 graphics card with openSUSE 42.2 and GNOME 3.20.2. I'm using the default open source driver. The AMD proprietary driver doesn't support 42.2. It's better than it was in 13.2, but I'm getting is a frequent horizontal flicker. Usually a few minutes apart. Is there a tweak for GNOME that might settle this?

Hi Jon Could try amdgpu? Or create a /etc/X11/xorg.conf.d/20-radeon.conf and add a tear free option?
I'm using amdgpu (obs compiled amdgpu kmp and later xf86-video-amdgpu) with a R5 Mullins card on a DELL Inspiron 5555 laptop and it runs great.

The amdgpu driver is installed already, but lsmod indicates that the radeon driver is loaded.
~> lsmod | grep radeon radeon 1601536 3 i2c_algo_bit 16384 1 radeon drm_kms_helper 155648 1 radeon ttm 106496 1 radeon drm 393216 13 ttm,drm_kms_helper,radeon
How would I switch this?

Hi Create 20-amdgpu.conf and 50-radeon.conf files containing;
cat /etc/X11/xorg.conf.d/20-amdgpu.conf;
Section "Device" Identifier "AMD Graphics Core Next GPU" Driver "amdgpu" Option "DRI" "3" Option "TearFree" "true" EndSection
cat /etc/modprobe.d/50-radeon.conf; blacklist radeon
Rebuild initrd;
mkinitrd
If it doesn't work you may need the later xf86-video-amdgpu as well.
What is the engineering name of your card (lspci output)? If it's GCN 1.0 series, may need to wait until 4.10 kernel... https://www.x.org/wiki/RadeonFeature/
