    Re: HOWTO: change resolution/refresh rate in Xorg

    YES!!!!!!!!!!!!!!!!!

    I HAVE SPENT LIKE 4 HOURS TRYING TO DO THIS!!!!

    Here is what I did (after installing Guest Additions):

    1) Terminal:
    Code:
    sudo gedit /etc/X11/xorg.conf
    2) Found the line with:
    Code:
    SubSection "Display"
            Depth        32
    3) Simply added this line below the Depth line:
    Code:
            Modes      "1366x768_60.00"
    4) Then rebooted.

    Automatically is was fixed!!! It was so simple!!! =D =D =D

    NOTES:
    a) My screen max resolution is 1366 x 768.
    Change that to your desired resolution

    b) My screen max refresh rate is 60Hz.
    Change that to your refresh rate.

    THANK YOU OP FOR GIVING THE IDEA!!!

    Hi, After a long time without using Linux as my main OS, I decided to switch back to Ubuntu, because of its user friendliness...

    Anyway, it would be great if someone could help me with this weird problem I am having:

    When I login to X with my 2 monitor setup, and a Radeon HD 5450 video card, my second screen (the one with the "Applications, Places, System" panels) looks all funny except for the panels. When I then change the refresh rate of my monitor to 60Hz and back to 75Hz all is fine and gets displayed properly. I'm thinking here there must be a bug in the proprietary driver, so I thought, maybe an easy solution would be to write a little bash script, which changes the screen resolution to 60Hz for a few seconds and then back to 75Hz, only I haven't found a command to do that. It's really annoying that I have to change the refresh rate on every boot manually, so please help if you know the answer to this question. All I need is a one-liner to change the refresh rate. And btw, changing it to 60Hz permanently has the same problem.

    I was pretty impressed how Ubuntu auto-detected everything. But this bug is really annoying, so please help.

    Thanks for reading in any case.

    Hi

    All I need is a one-liner to change the refresh rate.
    No idea if this will work for you but investigate this ....

    Code:
    xrandr --rate 60
    xrandr --rate 75
    Please post back results.

    Kind regards

    Hi, Thank you so much for replying so quickly!

    However, when I execute (with output):
    Code:
    $ xrandr --rate 75
    $ xrandr

       640x480        75.0     72.8     67.0     59.9
    it makes my left screen turn off. It's almost what I wanted, but I would need it to leave my left screen on. Any ideas?

    Thanks for your help so far!

    Re: HOWTO: change resolution/refresh rate in Xorg

    Just a follow-up:

    If someone has the same problem, switching the monitors around physically seems to have fixed this issue at the root. Maybe something to consider testing for the next Ubuntu release...

    EDIT: Sorry, this is wrong information, the monitor still does this. Maybe the monitor has an issue though, because it also makes a weird high-pitch noise.

    Sorry. I managed to lose your post. Maybe it is a monitor issue. Unfortunately i only have one monitor so i am not able to test.
