Public bug reported:
Ubuntu 3.19.0-15.15-generic 3.19.3
On boot, there are error messages from the radeon driver (see dmesg
output), and lightdm fails to start the X server - it simply hangs
without errors. Logging in on the console and running startx works, but
if the screen saver kicks in, the X server hangs again and needs to be
manually killed and restarted.
This started happening after one of the two latest kernel upgrades on
vivid, I didn't reboot after the -14 update, so I don't know whether
that or -15 caused this.
Please contact me If further information is needed, I can't attach more than
one file.
