Userspace is not a problem here, many distributions have GL implementation switch tools already.
I have users reporting that 6.14.4 suffers from the problem reported here. Basically, radeon.ko is loaded by X with KMS enabled, (CONFIG_DRM_RADEON_KMS=n but modprobe.d/ contains "options radeon modeset=1") but X fails to start with: (EE) RADEON(0): [dri] RADEONDRIGetVersion failed because of a version mismatch. [dri] This chipset requires a kernel module version of 1.17.0, [dri] but the kernel reports a version of 2.16.0.[dri] Make sure your module is loaded prior to starting X, and [dri] that this driver was built with support for KMS. [dri] Aborting. The problem is that xf86-video-ati is built with KMS and radeon.ko loads with modeset=1 but still, X fails to load due to the initialization (bug?) issue reported by the OP. Restarting X fixes the problem. I do think there is something to fix here and it would be nice to at least fix this chicken/egg issue. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/534662 Title: [RV635] No hardware acceleration on ATI Radeon 3650 HD using 'radeon' driver To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/534662/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
