 |
|
I just upgraded to 2.6.24-gentoo-r3, and everything seems fine except the boot process. When the uvesafb driver kicks in at the beginning of the boot, I get a blank screen. The system is booting but there is nothing on the screen and my monitor displays: "out of range." When X starts up, KDM starts and everything works okay. But if I press ctrl-alt F1 there is nothing there. No login, no nothing. Pressing ctrl-alt F7 brings me back to X with no problem.
I copied my old config (2.6.23-r8 ) and then used make menuconfig, and nothing seemed out of place. Am I missing some change with the uvesafb driver, or grub.conf?

everytime you copy your old config file to the new kernel directory you should do a
it shows you the changes between the 2 kernels
hope it helps you with your problem

did you have fbcondecor in kernel before? There are options that need to be enabled in the kernel:
| Code: | CONFIG_FRAMEBUFFER_CONSOLE=y
# CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY is not set
# CONFIG_FRAMEBUFFER_CONSOLE_ROTATION is not set
CONFIG_FB_CON_DECOR=y
|
maybe you should remove quiet and add splash=verbose and see what it shows. if you are currently inside X, you can also print output of:
| Code: | # cat /sys/class/graphics/fb0/modes
|

Yes all that was/is set.

I tried that and there was no difference. I will try some things later when I have some time. In the mean time my older kernel is working just fine.

I think your mode specified on grub line may be wrong. |
