Problems with Intel Video Resolution on Acer Laptop Wide Display
- by ricstr
I have an ACER Aspire 5332 laptop which I have just installed Ubuntu 12.04 x64, which is causing some issues with the video display on boot and video resolution.
First and foremost, it will only boot past the purple screen if GRUB has been edited to replace 'quick splash' with 'nomodeset'. Secondly, once it has booted with the the 'nomodeset' option, it does not allow me to change the resolution higher or lower from 1024 x 786.
Is it OK to use the 'nomodeset' for normal use? Will this compromise performance of other devices?
The video card is an on-board one, integrated within the Intel GL40 chip-set. The display is a wide-screen LCD, and under Windows could operate under various resolutions. Ideally I would like it to operate on a resolution to fit the wide-screen display as it a bit stretched out at the moment, and less desktop space as I am used to.
I believe the optimal resolution is 1366 x 768. Below is some information from the terminal which may be useful.
