They are fine, just normal chatter you get in there. However, the /var/log/messages does contain some issues with the video driver e.g.: Dec 22 09:43:37 elitebox kernel: radeon 0000:01:00.0: ring 0 stalled for more than 10221msec Dec 22 09:43:37 elitebox kernel: radeon 0000:01:00.0: GPU lockup (current fence id 0x00000000000002f3 last fence id 0x0000000000000302 on ring 0) Dec 22 09:43:37 elitebox kernel: radeon 0000:01:00.0: ring 0 stalled for more than 10722msec Dec 22 09:43:37 elitebox kernel: radeon 0000:01:00.0: GPU lockup (current fence id 0x00000000000002f3 last fence id 0x0000000000000302 on ring 0) Dec 22 09:43:38 elitebox kernel: [drm:r600_ib_test [radeon]] *ERROR* radeon: fence wait failed (-35). Dec 22 09:43:38 elitebox kernel: [drm:radeon_ib_ring_tests [radeon]] *ERROR* radeon: failed testing IB on GFX ring (-35). That's indicative of either a GPU (i.e. graphics card) problem or a driver issue. You can search on the 2nd from last line and there are lots of hits on it but no real solution - I've seen "limit memory use to 3G", "change PCI slot", "OpenGL bug" to "buy different card". > > I don't know what any of this has to do with Mate, but would appreciate > your assistance.

If that works OK using an updated Radeon kernel driver then you know the hardware is OK.
