some more details:
- no suspicious warnings or errors in /var/log/Xorg.0.log found
- when switching to tty[1-6], my display says:
Code:
frequency out of range: 65 khz / 52 hz,
please change the display mode to 1600x1200 with 60hz
i then checked the specs for my display and while the 65 khz (horizsync) are within the specificiations, 52hz (vertrefresh) is too low and the minimum accepted frequency would be 56hz.
my modelines in xorg.conf should be fine though, Xorg.0.log says
Code:
(II) NVIDIA(0): Assigned Display Device: DFP-0
(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0): "1600x1200@60"
(II) NVIDIA(0): "1280x1024@60"
(II) NVIDIA(0): "1024x768@70"
(II) NVIDIA(0): "800x600@70"
(II) NVIDIA(0): "640x480@72"
(II) NVIDIA(0): Virtual screen size determined to be 1600 x 1200
which looks fine to me.
also a bit further above in Xorg.0.log i find
Code:
(II) Loading extension XFree86-DRI
(II) LoadModule: "nvidia"
(II) Loading /usr/lib/xorg/modules/drivers//nvidia_drv.so
(II) Module nvidia: vendor="NVIDIA Corporation"
compiled for 4.0.2, module version = 1.0.0
Module class: X.Org Video Driver
this also appears correct
then there are two entries that i am not sure about:
Code:
(II) Loading sub module "fb"
(II) LoadModule: "fb"
(II) Loading /usr/lib/xorg/modules//libfb.so
(II) Module fb: vendor="X.Org Foundation"
compiled for 1.4.0.90, module version = 1.0.0
ABI class: X.Org ANSI C Emulation, version 0.3
(II) Loading sub module "wfb"
(II) LoadModule: "wfb"
(II) Loading /usr/lib/xorg/modules//libwfb.so
(II) Module wfb: vendor="X.Org Foundation"
compiled for 1.4.0.90, module version = 1.0.0
ABI class: X.Org ANSI C Emulation, version 0.3
well, fb probably stands for framebuffer and from what i found out until now, a framebuffer is what is needed for the vitual tty consoles. i just wonder if these are the right ones or if they somehow interfere with vesafb???
one thing that i would like to find out is where the 52hz vertical refresh come from, they are certainly NOT from the modelines i added. but i guess this must be set somewhere, so if anybody has a clue where, please let me know!
