[Solved] new X.org and resolution

Another "The new X.org is broken" post neutral

Actually, it's not so much broken as annoying -- since the upgrade, x.org insists on setting my resolution to 720*400, which is kinda strange on a 4:3 screen. If I change it with xrandr, it works afterwards. I have a list of modes in my xorg.conf, and it does not include 720*400.

Has anyone got any ideas? Is it possible to block a specific resolution from being used?

[Edit]
Actually, Option "PreferredMode" worked great -- but I had to add the corresponding ModeLine to the Monitor section. Others with problems with the new Xorg should check the debian wiki -- start at http://wiki.debian.org/XStrikeForce/HowToRandR12

Re: [Solved] new X.org and resolution

Hi gnud,
try to remove the line with the modes in your corg.conf file and restart X

Re: [Solved] new X.org and resolution

I've got something similar happening. Since yesterday I haven't been able to run my external flat panel at its default 1680x1050. That resolution is no longer listed under the options shown when I use KDE's control center.

I haven't changed xorg.conf or any other config files.

However, I have updated the following packages:

    xorg-server (1.2.0-5 -> 1.4-4)
    fglrx-utils (8.40.4-1 -> 8.42.3-1)
    xcb-proto (1.0-1 -> 1.1-1)
    libxcb (1.0-2 -> 1.1-1)
    libx11 (1.1.3-4 -> 1.1.3-5)
    mesa (6.5.2-1 -> 7.0.1-1)
    renderproto (0.9.2-1 -> 0.9.3-1)
    xf86-input-keyboard (1.1.1-1 -> 1.2.2-2)
    xf86-input-mouse (1.2.1-1 -> 1.2.3-1)
    xf86-video-ati (6.6.3-3 -> 6.7.195-1)
    xf86-video-vesa (1.3.0-1 -> 1.3.0-5)

I'm running the radeon driver for my Thinkpad's ATI X300 graphics chip. Is one of my updates the culprit? Is there a solution other than rolling back? Thanks.

Well, I took the coward's way out and rolled back all of the above packages, then listed them to be ignored in /etc/pacman.conf. I've got my nice screen rez back now -- after a reboot; it wasn't enough just to restart X. I'm hoping a resolution (of the problem, that is) will be forthcoming. If there's something that particularly needs testing, I'd be happy to do so with guidance.

Thanks.

Re: [Solved] new X.org and resolution

To set a default resolution you now have to put this line in /etc/X11/xorg.conf, in the section "Monitor":

Option    "PreferredMode" "1280x1024"

(with your preferred resolution, of course).

I hope that works.

I'm not the OP, but with my apparently similar problem, this option line didn't fix things. I still had to roll back the files that I listed in one of my posts above.

I hope your solution helps the OP, though.

[I hope I'm not guilty of thread-jacking; I thought our two problems were similar enough to merit being in the same thread.]

Re: [Solved] new X.org and resolution

Well, Option "PreferredMode" sounded good, but locked up X altogether -- I couldn't even switch to a VT, and had to ssh in to get my 'puter working again tongue

Before anyone asks, I have a radeon 9200, so it should be well supported.

I can't imagine that removing the modelines will solve anything, since they are exactly the same ones that X.org decides my monitor supports, minus the 720x400 one.

I'll test with Vesa and Option "PreferredMode", and check back with you. In the meantime, any suggestions are more than welcome.

Re: [Solved] new X.org and resolution

I'm starting to think this is a bug, tho. I mean, should X.org really choose 720x400 when my monitor and gfx card supports all modes up to 1600x1200? In the last x.org version, it chose the highest mode when I did not specify any modes in xorg.conf

Re: [Solved] new X.org and resolution

What's the output of "xrandr -q"? It should list all your available modes. Does it list the correct one? if so, does it work if you:

xrandr -s 1280x1024

(using your correct resolution)?

Re: [Solved] new X.org and resolution

Bogart, it does. The point was that I wanted X to start up in that mode, every time. Even with a display manager. It's solved now though - see the update in the first post.
