Title:
on login, X goes to blank screen, regression in 14.04
Status in “xorg” package in Ubuntu:
Confirmed
Bug description:
Note: this occurs when booting the 14.04 desktop installer ISO as
well, not just on the installed system. Booting any of 13.10, 12.04
or Fedora 20 does not exhibit the same problem on the same machines.
For the installed system, after logging in, the desktop comes up and
works for a few seconds (~10) and then the screen goes blank (and
switches to power save). Switching (Ctl-Alt-1) to a text console and
back will sometimes bring the graphics display back, and sometimes
won't. When the display is restored, it exhibits one or more of the
following:
- popup "could not switch the monitor configuration, could not set
the configuration for CRTC 63"
- executing "xrandr" (no arguments) causes the display resolution to
flip between 1280x1024 and 1440x900
- works for a short while, then goes black again
Examination of the Xorg.0.log shows that during the initial blank
screen time, X is rapidly cycling back and forth between those two
resolutions:
[ 37.124] (II) intel(0): resizing framebuffer to 1280x1024
[ 37.128] (II) intel(0): switch to mode 1280x1024@76.0 on VGA1 using pipe
0, position (0, 0), rotation normal, reflection none
[ 37.476] (II) intel(0): resizing framebuffer to 1440x900
[ 37.476] (II) intel(0): switch to mode 1440x900@59.9 on VGA1 using pipe
0, position (0, 0), rotation normal, reflection none
[ 37.784] (II) intel(0): resizing framebuffer to 1280x1024
[ 37.785] (II) intel(0): switch to mode 1280x1024@76.0 on VGA1 using pipe
0, position (0, 0), rotation normal, reflection none
[...]
This has occurred with two machines (with similar hardware, Intel Core
2 Duo with embedded graphics) connected to a particular monitor (a
Lenovo L194, 4434-HB6).
