sysrcd 1.6.0-beta001 boots always in 1024x framebuffer-mode

Post by gernot » 08 Jul 2010, 16:16

i dont know if this is a bug or a feature, but i'm not able to start to 80x25 console.
appending vga=0 dont work. The CD boots in 80x25 to the point where the modules are loaded. After this the screen get blanked and then popup
"delaying 1 sec" or something like this in a 1024x768 framebuffer.
On small monitors (my old :-) ) this fonnt looks darkgray on black.

is there a switch to avoid this modesetting?

You can boot with "nomodeset" but the new KMS drivers (intel, radeon, nouveau) are now the standard drivers, and it's even not possible to use the recent intel_drv in xorg without the intel KMS kernel driver. sysresccd-1.5.x had a quite old intel driver so this upgrade was required to switched to xorg-server-1.8. There are also other KMS related boot options. You can try something like that "video=LVDS-1:800x600". The isolinux configuration file will have to be updated for the new KMS stuff anyway.

thank you,
"nomodeset" works perfect in consolemode, but if i start X with wizard the screen is verry dark.
The Resolution (1024x768) is set and X is working.
Switching to a textconsole restores the brightness ,X dimms the display verry dark.
The card is a ATI RV250 .
I will search google and second this with other hardware....

video=LVDS-1:800x600 dont change the resolution

It's documented on the official KMS website
Try something like video=800x600 it seems to work

yes, it works :-)
The X-display is now a little bit darker and good usable.
By time i will check monitor,card and software for the problem.

Thanks for adding the bootentry to disable KMS
Now the console is bright as normal.

One side effect is that the display stay near black with wizard->Xorg-mkx
I dont know this problem happens only on my hardware (RV250).
Commenting out the line
DefaultColorDepth 16
in /etc/X11/xorg.conf makes the display bright with the next startx.
