10.10 and "nomodeset"

[kamuz]

Hello everyone,

When using 10.04 the "nomodeset" worked fine. I added "vga=0 nomodeset" to my grub config file so I could have nice 80x25 VGA in my terminal but still a high resolution using the X server.

But after upgrading to 10.10 and using "nomodeset" makes the X server to stop working or in this case, GDM won't even start.

Even manually installing the i915 module after rebooting can't make GDM to start again.

This is very frustrating as I really need the 80x25 in my text terminals.

Anyone knows a workaround for this? other than downgrading to 10.04


Thank you.

I think the vga may be the issue:

"VGA Deprecated" Message on Boot

http://www.gnu.org/software/grub/manual/grub.html
On x86 systems, the kernel will be booted using the 32-bit boot protocol. Note that this means that the ‘vga=’ boot option will not work; if you want to set a special video mode, you will need to use GRUB commands such as ‘set gfxpayload=1024x768’ or ‘set gfxpayload=keep’ (to keep the same mode as used in GRUB) instead. GRUB can automatically detect some uses of ‘vga=’ and translate them to appropriate settings of ‘gfxpayload’. The linux16 command (see linux16 (http://www.gnu.org/software/grub/manual/grub.html#linux16)) avoids this restriction.

Hello,
Thanks for your reply.
Because I upgraded my installation (since 8.04) I never got grub2, still using 1 (grub-legacy) so the VGA option should work.
Just for the kicks, I removed the VGA option and only used "nomodeset" and still didn't work.

I still don't understand what was the change between 10.04 and 10.10 for this to stop working.

Is there another way to set the console resolutions to be different than the one in the X server?

Thanks.

I have not gotten into the details of xorg.conf for many versions, but I think that is what you have to look at.

Did you accept maintainers version on upgrade and still have a backup in /etc/X11/xorg.conf?
