Only 640x480 screen resolution on ubuntu 5.10

nickleus · 01-23-2006, 09:10 AM

Hi again, i just installed ubuntu 5.10 and i can't get a larger screen resolution than 640x480. it sucks.
i ran the following command:

Code:

xresprobe nvidia

and got this output:

Code:

id: Acer AL1911
res: 1280x1024 1024x768 832x624 800x600 720x400 640x480
freq: 24-80 56-75
disptype: lcd/tmds

i tried to edit my xorg.conf by adding the horizsync and vertrefresh, but to no avail.

My xorg.conf looks like this:

Code:

Section "Device"
        Identifier      "VIA Technologies, Inc. VT8378 [S3 UniChrome] Integr$        
        Driver          "via"
        BusID           "PCI:1:0:0"
EndSection

Section "Monitor"
        Identifier      "Acer AL1911"
        Option          "DPMS"
        HorizSync       24-80
        VertRefresh     56-75
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Device          "VIA Technologies, Inc. VT8378 [S3 UniChrome] Integr$        
        Monitor         "Acer AL1911"
        DefaultDepth    24
        SubSection "Display"
                Depth           1
                Modes           "1280x1024" "1024x768" "832x624" "800x600" "$        
        EndSubSection
....
....
plus other depths that look the exact same...

any help? i think the monitor/card can handle 1280x1024. another thing too. the monitor/screen is all wavy and is really annoying! why is it doing that?

To me, it looks like it does not recognize your graphic card (but I may be wrong after all)

I have the same Acer 19'' lcd display with an Nvidia GeForce4 card: The Ubuntu installing program recognized configured everything right.
Try installing Automatix and letting it install Nvidia drivers:

Code:

wget http://beerorkid.com/automatix/automatix-ubuntu_4.3-1_i386.deb
sudo dpkg -i automatix-ubuntu_4.3-1_i386.deb

then you go to the System Tools menu, run Automatix an choose what you want it to install and configure automatically.

To remove automatix:

Code:

sudo apt-get remove automatix

Serch for answers www.ubuntuforums.org as well.

Thanks Luke771, how do i know if it *does* recognize my card or not? is there any kind of command that checks that? i'll install that automatix and see what happens. i checked the ubuntuforums.org earlier today, but it was down for maintanance reasons =)

nickleus did you fixed the problem? Because I have the same problem on my fedora core 4

nickleus:

I don't know anything about automatix, but I think you can try reconfiguring X (which I presume is the key problem) and uncheck everything but the 1280x1024 option at the point where you're asked which resolutions to use. Try and follow:

Code:

$ sudo dpkg-reconfigure xserver-xorg

If this doesn't help: Your graphic card seem to use a VIA chipset (as of the listing of Xorg.conf - you can check if it's recognized correctly by doing:

Code:

$ lspci

If your video adapter isn't listed correctly, you can always try the NVIDIA thing.

Apart from that, I'd be interested in the handling of automatix, too, btw...

oldsko0l:

This doesn't hold for you, sorry - it's a Debian/Ubuntu thing (except for lspci, of course).

oldsko0l · 02-19-2006, 03:13 PM

nono, but the xorg.conf thing is the same so maybe

I was just hoping, because nowere on the net somebody can help me

oldsko0l:

Try to remove anything in the Modes line(s) except for the resolution you want. It's not without risk, but it's worth a try. You can always reedit your xorg.conf and put everything back in...

As far as I experienced similar things, it's only happening with older (or brand new) video adapters (or generic or quirky ones - laptops, mostly).
