Does restarting X fix te issue?
I can't restart X, it hangs when I try, xrandr also hangs. Even kill -9 doesn't kill it. The logs sometimes don't show anything at all but today it's show this consistently: un 20 18:19:08 navi kernel: [drm:cik_ring_test] *ERROR* radeon: ring 1 test failed (scratch(0x3010C)=0xCAFEDEAD) Jun 20 18:19:08 navi kernel: ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300) Jun 20 18:19:08 navi kernel: ata1.00: configured for UDMA/133 Jun 20 18:19:08 navi kernel: [drm:cik_ring_test] *ERROR* radeon: ring 2 test failed (scratch(0x3010C)=0xCAFEDEAD) Jun 20 18:19:08 navi kernel: [drm] ring test on 3 succeeded in 4 usecs Jun 20 18:19:08 navi kernel: [drm] ring test on 4 succeeded in 4 usecs Jun 20 18:19:08 navi kernel: [drm] ring test on 5 succeeded in 1 usecs Jun 20 18:19:08 navi kernel: [drm] UVD initialized successfully.

That log is gone but it had a message basically saying (I don't remember the exact words) that something went wrong and the kernel recovered but a reboot was still needed. I'll post if it comes up again. Also relevant that I've been getting this and similar errors on my logs for a few days (probably since I switched to the radeon driver), all the i2c devices are on the video card: Jun 20 16:46:30 navi kernel: i2c i2c-7: sendbytes: error -110 Jun 20 16:46:41 navi kernel: i2c i2c-7: sendbytes: error -110 Jun 20 16:47:01 navi kernel: i2c i2c-7: sendbytes: error -110 Jun 20 16:47:11 navi kernel: i2c i2c-7: sendbytes: error -110 Jun 20 16:47:31 navi kernel: i2c i2c-7: sendbytes: error -110 -- Fernando Rodriguez
