X and framebuffer: distracting lines after x restart

Hello.
I've appended vga=792 to my kernel boot line. Everything works as expected. In console mode I've got a nice resolution and X is starting flawless.

But when I kill X and want to restart it, there is a annoying graphic bug:
Take a look at the very first "lines" of my screenshot. Especially annoying because those line triplets are blinking. <:

This I caused by the framebuffer because without appending vga=792, I can restart X as often as I want to, without having this problem.

Any suggestions? (-:

Re: X and framebuffer: distracting lines after x restart

Same kind of problem here, but it seems somewhere related to splashy :

title  Arch Linux
root   (hd0,5)
kernel /boot/vmlinuz26 root=/dev/sda6 rw vga=791 
initrd /boot/kernel26.img

is okay, but I get the lines when I use (without changing anything else) :

title  Arch Linux
root   (hd0,5)
kernel /boot/vmlinuz26 root=/dev/sda6 rw [b]quiet splash[/b] vga=791 
initrd /boot/kernel26.img

Fortunately the lines aren't blinking in my case and they disappear when I logout and login again in my gnome session.
Hardware is and ati radeon 9200 (free xorg driver).

how do u know this is caused by the framebuffer. It could easily be your video driver unless I'm mistaken. Do those lines remain there indefinitely? What if you switch to console two times successively.

Re: X and framebuffer: distracting lines after x restart

Well... using this kernel boot line, I get those lines after I restart my X server:

kernel /vmlinuz26suspend2 root=/dev/sda4 ro vga=792 resume2=file:/dev/dm-0:0x44b448

Using this kernel boot line, I can restart X as often as I want to without getting these lines:

kernel /vmlinuz26suspend2 root=/dev/sda4 ro resume2=file:/dev/dm-0:0x44b448

Note that I just removed "vga=792". I think it's framebuffer related, because as far as I know that vga=xxx makes the kernel to boot in a framebuffer mode or am I mistaken?

My graphic card is a NVIDIA Go 7600. I am using nvidia-96xx drivers and the supsend kernel.

Re: X and framebuffer: distracting lines after x restart

Hi, I have a very similar problem, I have a laptop with wide screen and a geforce go 6100, i have been runnig nvidia driver, because de readme file saids that my card is supported, but when going back to frame buffer (anyone)I got a blak screen. Now i'm runing nvidia-96xx, is a bit slower to start but i work well. Now when i go back to frambuffer 791 i get annoying lines in the tty, so i removed the vga=791 from grub, now if i dont restart X when i go back to frame buffer i have the console's color change, eg: red background and green text, always differents colors. Kind of grovie
After restarting X is all just normal.
I almost forgot!With vesa driver there are no problems with framebuffer or anything.
Is there another way of fixing this?, I really like using vga=791, and the funky colors in tty are cool, but im getting tired of them...
