    Ubuntu update broke screen resolution

    Okay, this is annoying.

    I'm running Ubuntu 12.04 LTS. The box it's installed on uses onboard Intel video, and I normally use XFCE4 as my desktop.

    I have a 27" AOC monitor that uses 1920x1080 as the standard resolution. It was a replacement for a failed Viewsonic, and I was delighted when I attached it and Ubuntu detected the resolution and used it.

    It worked fine until half an hour ago, when Update Manager informed me there were updates and I installed them. One broke screen resolution: Ubuntu now refuses to admit the monitor will do more than 1024x768.

    I recall having this issue before on another machine that did 1280x768 native, and a Ubuntu 11 series update reduced it to 1024x768. I never was able to track down what the problem was - poking around in system logs showed that Ubuntu knew the hardware could do the higher resolution, but nothing I did from the desktop would make it do so. The problem got resolved in a subsequent release.

    Is there a known fix for this? Upgrading to 12.10 is not currently an option.

    Thanks in advance.

    [SOLVED] Re: Ubuntu update broke screen resolution

    And this may be even more annoying.

    Googling on related issues pointed me at some things I could try. When I switched back to the Ubuntu box, the problem had mysteriously solved itself. Suddenly, 1920x1080 was was a resolution selectable from the display properties box, and I could set it and have things back to normal.

    No, I have no idea what was going on. No, I have neither the time nor energy to dig around and find out. I have a correctly configured box again, and I'll settle.

    Consider this solved, and sorry for the waste of bandwidth.
