Low resolution on Intel mobile 4 and Lubuntu 12.04 64 bit

Asked by stefano.fraccaro

I have a newly installed Lubuntu 12.04 64 bit but LXRandr has only 1024x768 resolution available.

I can't switch to 1366x768 that is the best resolution for my ACER 5735 laptot.

I have tried xrandr from the command line without success: I can choose the new resolution from LXRandr but the monitor don't change resolution.

I'm missing something? There is something to install?

Best regards
Stefano

You may need an xorg.conf file if your monitor isn't doing what it should do.

https://wiki.ubuntu.com/X/Config/Resolution don't resolve my problem. Max resolution is not correctly detected and when I create a new resolution for 1366x768, cvt create a resolution of 1368x768 that is not supported by this monitor

I solved this using this tutorial http://www.icpep.org/mobile-series-4-display-problem-on-ubuntu-10-10-or-higher/ but after updating the OS yesterday everything is messed up.. Wish I did not include xorg updates :(

:D I removed the driver on software center named: X.orgXserver -- intel i8xx, i9xx, display driver and all dbg symbols. I also removed all VAAPI driver for intel G45 & HD Graphics. Its back to normal, I think the update previously installed this drivers after the update. I'll be careful from now... I'm using acer aspire 4736...
