    Screen resolution problem: fglrx / EnvyNG / Automagix

    Hi
    Having puzzled whether to get a new mac or pc , I've gone for keeping the old dell laptop and using Ubuntu. So far so great, except for a couple of problems.

    Screen resolution. I've tried the normal a number of changes to xorg.conf with no success. Nothing looks ok when I click the 'Test'button, whatever I do, there is no res higher than 800 x 400 in the menu. What do I do next? There seem to be a number of options

    1) Install the fglrx driver - what is this exactly?
    2) Start using EnvyNG - could this cause upgrade problems?
    3) Use Automagix - not recommended by Ubuntu?

    Any tips or advice out there?

    https://help.ubuntu.com/community/XORGHardy may give you some information. As far as your item #3 is concerned, Automatix is gone, which, to me, is a blessing.

    Thank you so much for providing this link!!!

    I have been using "X" since it was invented (yes - I am that old....!) and have been completely baffeled by the sudden inability to change anything from the now useless "xorg.conf" file.

    I had figured out that there had been some major change in the configuration process, but this information was not disclosed in a BIG, BRIGHT, announcement during the upgrade process - as it should have been.

    Probably 3/4 of the video problems folks are having with Hardy are the result of this MAJOR change that users are simply unaware of.

    Again, thanks so much. I hope the Ubuntu team will do more to make this critical change information common knowledge in the Ubuntu community!

    BTW, I am having the same problem as the querent in this thread, but with an old Matrox G450 Dual-Head AGP card.

    see my xorg.conf below.

    I had to manually enter a bunch of modes to be able to switch to different resolutions as the default was only 640x480.

    One thing to try regarding screen resolution; from the command line
    Code:
    gksudo displayconfig-gtk
    and see if the vendor and model of your monitor is listed; if so, select; if not, try a generic monitor description that is close, input the resolution desired and apply. Also, while in that app, take a look at the graphics card tab to see if the correct card (or the series for the correct card) is being detected.

    this was the solution , but it took a surprising number of iterations to get here, several times I made what seemed like sensible changes but made no difference - then suddenly a pop up informed that 'all users need to log out for changes to take effect' and bingo, all came good. All this was after a lot of time spent wasted on xorg.conf - which doesnt seem to do anythying. Anyone else working with this should definitely study https://help.ubuntu.com/community/XORGHardy for tips.

    Thanks to all for the help and suggestions - much appreciated!
