Public bug reported:
Every time I put my laptop to sleep and wake it up again I am presented
with the graphical login prompt as expected. The prompt works, I have a
mouse, keyboard works, etc. Once I successfully login the display turns
black and remains that way no matter how long I wait. The computer is
responsive and I can switch to a tty. Switching to a tty and then back
to the graphical desktop does not produce anything (screen remains
black.)
>From the TTY I've tried to configure X manually using xrandr and the --display
>argument:
`xrandr --output LVDS1 --mode 1366x768 --pos 0x0 --rotate normal --display :0`
This gives me the error "xrandr: Configure crtc0 failed". Note that
1366x768 is the native display mode of my monitor. If it matters I'm
using the i915 driver (I have an intel graphics controller, revision 9).
If I run this command after a successful boot, it works (I can change to
a different display mode and then back again no problem).
Logs don't seem to have anything interesting in them; but I may not be
looking in the right logs at the right time. Guidance needed :)
If I reboot the computer from the tty; I get the xfce graphical shutdown
screen.
I'm currently running xubuntu 14.04. This laptop used to run xubuntu
12.10 without issue.
