 Posted: Wed Aug 22, 2012 12:14 pm Post subject: [Solved] Grub 2 and ati-drivers |
 |
|
Hi all,
I have decided to switch from lilo to grub2 (basically to have an higher resolution background), all worked fine on my workstation that use Ati opensource driver (KMS) but on my laptop that use ati-drivers (I have to use for university, I need the best performance, F**K proprietary driver) I have a strange problem.
Using lilo when I press enter it starts booting, no big problem only the resolution is very low (the words are huge) but was good to enter username, password and type startx.
Now with grub2 when I press enter it displays a distorted version of the background that I set for grub, unlike my workstation in which I see all the boot process, I don't see anything else but if I wait 20-30 seconds (the time to let it boot) and I type username, password and startx gnome starts as usual.
Any ideas?
This is my /etc/default/grub/
| Code: | GRUB_DISTRIBUTOR="Gentoo"
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=5
## Kernel option
GRUB_CMDLINE_LINUX=""
GRUB_CMDLINE_LINUX_DEFAULT=""
## The resolution used on graphical terminal
GRUB_GFXMODE=1920x1080x32
GRUB_GFXPAYLOAD=1920x1080x32
## Background image used on graphical terminal
GRUB_BACKGROUND="/boot/grub2/Wallpaper.png" |
Thanks

I'm also using the FGLRX driver. In case it's of any use to you, here are the contents of my /etc/default/grub file:

GRUB_DISTRIBUTOR="Gentoo"
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX="`cat /proc/cmdline | sed -e 's#BOOT_IMAGE=.* ro ##g'`"

GRUB_GFXMODE=1024x768

GRUB_BACKGROUND="/boot/grub2/mybackground.png"
# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to kernel
GRUB_DISABLE_LINUX_UUID=true

#GRUB_DISABLE_RECOVERY=true |
Another thing: My laptop screen resolution is 1920x1080 but, rather than mess around with different resolutions, I simply took a 1920x1080 image that I wanted to use for my GRUB 2 background, loaded it in the GIMP, selected Image > Scale Image..., unticked the link between Image Size Width and Height, changed the width and height to 1024x768 and saved the resulting distorted image as /boot/grub2/mybackground.png. When my laptop boots, the mybackground.png image get stretched back to 1920x1080 and looks correct as a result!

| Thanks for reply but adding "GRUB_CMDLINE_LINUX="`cat /proc/cmdline | sed -e 's#BOOT_IMAGE=.* ro ##g'`" " didn't help, same behavior. |

Seems that now it worked if I start using the battery and not AC.
That's quite strange. |
