HELP! Laptop graphics broken after update and reboot

Postby JustinGordon on Tue Mar 20, 2012 4:25 am

Very sadly and discouragingly, after updating to the latest Mint 12 updates, HP Pavilion DV7 will only boot one screen to 1024x768, whereas before rebooting I had 1600x900 and a 1080P second monitor.

System details:
Intel® Sandybridge Mobile x86/MMX/SSE2
Intel® Core™ i7-2720QM CPU @ 2.20GHz × 8

I have NOT installed the ATI/AMD proprietary FGLRX driver.

This is incredibly discouraging as I had thought Mint 12 to be an excellent Linux distro.

Is there any way to back out updates? Any ideas?

I seem to have fixed the problem with the following steps:
Go to "Displays"
1. Disable the 2nd monitor, apply
2. Set laptop screen to 1600x900. Apply (worked)
3. Unplug the 2nd monitor
4. Plug in the 2nd monitor
5. Click Detect Displays -- now shows correct resolution for the 2nd monitor.
6. Enable the 2nd monitor

Anyway, this is really super scary!
