    Resolution problem


    I was running linux mint on my 1600x900 screen with no problems whatsoever until yesterday - I turned on my PC and the resolution had changed for no apparent reason (In addition my wallpaper had resetted to the default one ??? )
    The width was extending outside the screen and the height was too low, leaving a black unusable area.

    Xrandr told me i was still using 1600x900. I tried changing/adding new resolutions but all of them made my eyes bleed.

    I tried deleting the 1600x900-mode (and re-add it) but then this happened:
    Code:
    sudo xrandr --delmode  CRT1 1600x900
    
    X Error of failed request:  BadAccess (attempt to access private resource denied)
      Major opcode of failed request:  141 (RANDR)
      Minor opcode of failed request:  19 (RRDeleteOutputMode)
      Serial number of failed request:  49
      Current serial number in output stream:  50
    I tried deleting the xorg.conf configuration file. Nothing happened.

    I both uninstalled and updated my GPU drivers, nope.

    I gave up and installed debian. The problems persisted. I tried Ubuntu, no luck there. How can this problem persist after formatting the OS partition, if i had no problems after my first install? I'm so confused... I should mention that my BIOS screen doesn't have this problem.

    Please help.

    What version of Mint? What hardware do you have? It was likely an update that changed something...
