Hello there i found out the radeon manpages isn't right in DRI section: Option "DRI" "integer" Define the maximum level of DRI to enable. Valid values are 2 for DRI2 or 3 for DRI3. The default is 2 for DRI2. Following that i couln't enable DRI3, cat .local/share/xorg/Xorg.0.log | grep -i dri3 will outputs: RADEON(0): DRI3 disabled But if one sets: Option "DRI3" "1" then cat .local/share/xorg/Xorg.0.log | grep -i dri3 will outputs: RADEON(0): DRI3 enabled So i think you should edit the manpages like so: Option "DRI3" "1" To enable DRI3 support... Thanks to all of you
It sounds like maybe your man pages and driver are out of sync. Option "DRI3" was the original option. Later support for Option "DRI" "3" was added for consistency with other drivers. https://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=f123096877f0a0044f3d0315285441f2b5790c29
