FGLRX edit

Disable FGLRX

fglrx is not supported in openSUSE Leap 42.2+. If you need to remove fglrx because of issues (e.g. X is unable to start) or prior to an upgrade, please follow these instructions to re-enable the open source radeon driver.

Remove Blacklist

One of the first things fglrx does to ensure that radeon doesn't interfere with it is it blacklists the radeon module so that the kernel doesn't load it while booting.

# rm /etc/modprobe.d/fglrx.conf

or

# rm /etc/modprobe.d/50-fglrx.conf

X11 Configuration

When fglrx is installed, aticonfig creates xorg.conf containing configuration details for running fglrx. The default configuration files are in /etc/X11/xorg.conf.d/, so it's ok, in this case, to completely remove xorg.conf.

# rm /etc/X11/xorg.conf

Load radeon

The next thing you'll want to do is to load the radeon module. Modprobe makes this easy:

# modprobe radeon

Restart X

Restarting X is relatively simple: Ctrl - Alt - Backspace + Backspace

Mesa edit

Mesa is the open source implementation of OpenGL.

Update Mesa

Updating Mesa may improve performance, especially on older versions of openSUSE.

Add Repository

Replace "42.3" with your version of openSUSE.

Perform Update

# zypper dup --repo X11:XOrg
