Created attachment 258591 [details] syslog System crash during startx. Normal because I don't have the firmware : radeon 0000:01:05.0: radeon_uvd: Can't load firmware "radeon/RS780_uvd.bin" Strange : kernel modesetting is usually disabled probably because the driver run in software mode due to the lack of firmware. But in Xorg.log it is enabled : [ 101.256] (II) [KMS] Kernel modesetting enabled.
