Title:
blinking blank screen after booting [asus zenbook ux21]
Status in linux package in Ubuntu:
Invalid
Status in linux package in Fedora:
New
Bug description:
Hardware: Asus Zenbook UX21e
Software: Ubuntu 12.04 LTS
This issue have begun from booting LiveCD - I've dowloaded iso, burned
it and loaded using external CD drive: screen was blinking couple
times during boot. However, after booting system seems stable, so
during installation wasn't any problems at all.
After first boot into installed system I've noticed the following behavior:
- display is blinking couple times during boot
- display is blinking couple times on lightdm login screen
- after login display also is blinking couple times, buf after this system
looks like usable and stable
The symptoms above is repeating each time on boot now, but *SOMETIMES*
display becomes totaly blank after blinking - it may be blank:
- during boot
- after boot, but before lightdm screen shows up (I can hear logon screen
sound when display is blank already)
- after login - I've entered login/password, desktop shows up, display is
blanking, and then display is never showing up again
- if i run 'xrandr' from terminal, then screen is blinking (probably, when
tries to detect supported resolutions) one time just as during boot
Some additional information:
- all currrent updates is installed
- screen is not black/turned off - it's *blank* (i can see LED light for
screen)
- I've tried another kernels from Kernel Mainline PPA
(http://kernel.ubuntu.com/~kernel-ppa/mainline/ : I've tested 'daily',
'drm-intel-fixes' and 'drm-intel-next' - no any success at all; behavior is the
same)
- I've tried another xorg-related packages from XOrg Edgers PPA - behavior
is still the same
- I can't see TTYs, if screen goes blank during/after boot - I can switch to
TTY 'in blind': ctrl+alt+f2, and it works, for example: type login/password,
run 'sudo reboot', type password; but on TTY screen is also blank
- switching to TTY's after booting and login in with 'working' screen may
cause screen to blank it
Non-working workarounds
(https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen#How_It_Works):
- I've tried to remove 'quite splash' from 'linux' line in grub config (by
editing /etc/default/grub and doing sudo update-grub)
- I've tried to add 'set gfxpayload=text' option in menu entry on boot using
grub
Working workaround:
- add 'nomodeset' to 'linux' line in grub config: after this no any issues
described above, system is booting stable, but, obviously, user has lost
additional graphics hardware acceleration and features
(unity-3d/compiz/compositing/etc), and that's very sad.
Similar bugs - although I can't google exactly the same issue, but looks like
that the following bug may be related to my issue:

I will be very appreciate for any confirmations; also I would like to help by
testing/providing necessary logs for fix this issue as soon as possible.
