on my thinkpad T400, Ubuntu 12.04 hangs after "Checking battery state" and I have to boot the unity shell using startx in tty1 . My video card is an Intel Gma 4500Mhd. I cannot reinstall Ubuntu (because I have big software installs). It came after an upgrade. Maybe it is a shell problem.
lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
When using the recovery mode root console, Xorg -configure leads to an error:
could not create lock file /tmp/tx0-lock
Can you help please?
mount -o remount,rw /it will remount the filesystem as normal, so do that and try the X command again - might give you a better error. – Tim Fountain Oct 9 '12 at 21:09mount -o remount,rw /I was able to run X -configure, it gives the error message :Number of created screens does not match number of detrected devices. Configuration failed. ....error(2)with or without my external VGA screen plugged in. – louis Oct 11 '12 at 12:22
