[SOLVED] Reinstalled GRUB, max screen resolution dropped to 640x480

[the dsc]

After I finally succeed reinstalling GRUB, when I was accessing the actual system, the resolution was only 640x480, already in the GDM.

The xorg.conf seems fine to me:

Which Distro are you using? You have to install Nvidia proprietary driver..

Are you passing any vga value to kernel?

Which Distro are you using? You have to install Nvidia proprietary driver..

Debian etch. Before I reinstalled grub, the resolution was just normal, I mean, the highest supported for this monitor.

Do you mean that maybe if I reinstall the driver it may fix whatever is wrong?

(well, at least I think it would be *re*install since it was working before)

Are you passing any vga value to kernel?

I don't know... I don't know what it means




Thanks anyway. Gotta love this forum, ready responses

Open /boot/grub/menu.lst file with root privileges and add vga=773 at the end of kernel line. Reboot machine.
Alt+F2 and type this

gksu gedit /boot/grub/menu.lst

[the dsc]

All it did was change the resolution before X/GDM starts... the whole boot "verbose" has now more lines and columns... (which I like anyway). The preferences within gnome also don't have more resolution options... xrandr also gives nothing but 640x480 and 320x240.

That's so weird... how something seemingly so unrelated could affect the resolution... I'm clueless.

You are using Generic Nvidia Driver 'nv'. Install proprietary Nvidia driver for better resolution.
If you dont want to install Nvidia driver, try replacing "nv" with "vesa" in xorg.conf file.

I'll try it, but I'm suspicious that's not the cause...... or else, how could be that it was fine despite of the fact that I didn't change anything about video drivers and things like that?

I hope I'm not sounding ungrateful, it's just that the whole situation is so weird...


If it does not work I think I'm going to reinstall. It's a fresh new installation anyway, so almost nothing will really be lost. I'll need to install windows in the near future anyway, and that probably would mess up GRUB again... so I think that if it does not work I should concentrate my efforts on studying which is the better sequence and other details to install both OSs in order to minimize the headaches.

And thanks!

It DID work!!

Wow, that's unexpected. I just hope it stays that way when I reboot... I've edited xorg.conf and restarted X, without rebooting... I don't see any reason why that would change with a reboot, but I still don't see why it happened in the first place, heh.

Many thanks.
