5.0 - unsufficient resolution

I just installed from a 5.0 Live-CD to the harddrive.  Using the Live-CD I had the correct monitor resolution of 1280 x 1024, but after booting from the harddrive it is only 1024x768.

I use an old Nvidia card

[blockquote]05:00.0 VGA compatible controller: NVIDIA Corporation NV44 [GeForce 7100 GS] (rev a1)[/blockquote]

lsmod shows that for video nouveau is used. The Xorg Vesa video driver is installed. But how to make use of it?

[blockquote]

root@slitaz:~$ ls /etc/X11/xorg.conf.d/

35-synaptics.conf  40-Keyboard.conf   40-evdev.conf      45-synaptics.conf

[/blockquote]

Any ideas available here?

Re: 5.0 - unsufficient resolution

5.0 live cd includes 2 video drivers xorg-xf86-video-fbdev and xorg-xf86-video-vesa

Check /var/log/Xorg.0.log when booted live with 1280x1024 compared to booted in the install at 1024x768 to see which video driver is in use.

I think "xorg-xf86-video-nouveau" driver is best choice:

http://root:root@tazpanel:82/pkgs.cgi?do=Install&xorg-xf86-video-nouveau

Also with default xorg-xf86-video-fbdev you can try video=1280x1024 kernel option.

Re: 5.0 - unsufficient resolution

Ok, when I boot from the Live-CD I see in Xorg.0.log that it seems to work with fbdev:

22.197] (**) FBDEV(1): using shadow framebuffer

But lsmod shows me that nouveau is loaded:

When I blacklist nouveau in the hard-drive install I do not get an X-screen.

Hopefully this information is sufficient?

Re: 5.0 - unsufficient resolution

Ok, the mistake is clear: the problem sits as usual in front of the machine! ;-)

From Slitaz 4 I was used that I have to run the kernel command line including „nomodeset" to get a sufficient good result. If I stop this when booting the harddrive installatio I get immediately the desired resolution!

The driver in use is nouveau!

Thanks a lot for you help!

Re: 5.0 - unsufficient resolution

What video driver is being used when you boot the install to 1024x768?

OK, glad you figured it out.

Re: 5.0 - unsufficient resolution

@mojo

Sorry, this I could not figure out. The driver nouveau had been loaded, but when the boot was done with the line including „nomodeset“ it went wrong. I was not able to interprete the contradictory results. Now it is perfect! ;-)
