[SOLVED] Command line resolution

[ubuntunix]

Greetings.

My home server (Squeeze) has a command line resolution of 1280x1024, but the graphics card only goes up to 1024x768 (it supports 1280x1024 but is quite old and no longer works at this resolution ). I've changed the resolution successfully for GRUB2, which didn't help. I also installed X and GNOME to verify that they work at 1024x768.

Finding a solution would be great, currently the system is only usable through SSH.

How did you change it for GRUB2? Making the change in GRUB2 should change it for the console.

"set gfxmode="1024x768" in /boot/grub/grub.cfg. Making the change for either GRUB or X doesn't seem to affect it.

Set the resolution in /etc/default/grub too.

vesafb is probably included in your kernel and is configured by adding "vga=____" to your kernel line in your grub file. This table lists resolutions and colors.

    | 640x480  800x600  1024x768 1280x1024
----+-------------------------------------
256 |  0x301    0x303    0x305    0x307   
32k |  0x310    0x313    0x316    0x319   
64k |  0x311    0x314    0x317    0x31A   
16M |  0x312    0x315    0x318    0x31B

You'll probably want 1024x768@16M so add to your grub configuration file, in the kernel line add this text:

vga=0x318

and you should be good. For more complex resolutions (widescreen and such) use uvesafb, but you should be fine with this configuration

the "vga=" option will cause grub2 to flag the command and warn you to use the set gfxmode option, which is the appropriate way of setting the grub2 video mode .

Didn't work, when the system is booting (post-grub) it is initally the correct resolution but then changes to 1280x1024. =\

Post the output of these commands :

grep -n GFX /etc/default/grub
grep -n GFX /etc/grub.d/00_header

[ubuntunix]

Post the output of these commands :

grep -n GFX /etc/default/grub
grep -n GFX /etc/grub.d/00_header

21:#GRUB_GFXMODE=1024x768

39:if [ "x${GRUB_GFXMODE}" = "x" ] ; then GRUB_GFXMODE=1024x768 ; fi
127: set gfxmode=${GRUB_GFXMODE}

The resolution reverts to 1280x1024 or similar right after "Waiting for /dev to populate"...

I'm having this same issue. It's not really a big problem in itself for me.
But it might be causing some other ill effects.
Happens at around the same time as the OP stated, and sometimes makes the screen scramble with vertical colored lines. Then after restarting X or reboot the screen locks up after 15-20 mins.
I think it's because I changed the display card.
It had an on-board display chipset and I added an Nvidia PCI card in an attempt to make KDE4 more responsive.
The BIOS has no option for disabling the on-board adapter, only lets me set it to initialize the PCI card 1st.
I assume this is the problem because it didn't happen at all until I put the PCI card in.

On a different note, it's aggrevating that this board has to load so many images that it prevents me from scrolling around the page because it always has a problem with a couple images loading.
It constantly says "Read images.kontera.com" but never finishes so navigating the page makes it seem like I'm on a Pentium Pro ca. 1995.
It all but disables the scroll wheel, and when I start reading the thread it all of the sudden goes to the absolute top or bottom of the page due to a huge delay in scrolling. Using the scroll bar is super slow too. Makes reading anything here difficult.
It's doing it right now as I'm trying to type.

Resolved the problem by simply installing nvidia-glx, but I don't see why this was necessary. It now runs at 1024x768.
