CentOS - X window problem

**satimis** · 03-17-2007

Hi folks,

CentOS 4.4 x86_64
LCD display – Philips Brilliance 200WP7
nVidia chipsets

The LCD display can't display correct resolution.

The xorg.conf on this PC is as follow;

# cat /etc/X11/xorg.conf

At time of installing CentOS I can't find my LCD display. Therefore I selected "Philips Brilliance 201(21inch/CM1700)” instead. I can manually edit it. But the major problem is on nVidia driver. I can download and install nVidia driver on nvidia.com website to fix the problem. Howevr if in future running update on kernel and/or xorg I have to reinstall the nvidia driver.

Is there an official nvidia driver. OR is there any other solutions. TIA

HorizSync 31.5 - 107.0
VertRefresh 50.0 - 170.0

does your Monitor support these resolutions? you have to install nVidia drivers for nest graphics performance and you have to re-install drivers on every kernel upgrade.

**satimis** · 03-17-2007

Hi devils_casper,

does your Monitor support these resolutions?

No. But I'm not allowed to make any change to xorg.conf on this section. Otherwise Xfce4 can't start. I just tested it.

My monitor;
resolution: 1680x1050
vertical: 56~76
horizontal: 30~98

you have to install nVidia drivers for nest graphics performance and you have to re-install drivers on every kernel upgrade.

I have many experience on nVidia driver running this ASUS EN7300 vedio card on archlinux, slamd64, freebsd6.2, etc. now CentOS 4.4. After upgrade kernel or xorg X can't start. Then I have to run the old xorg.conf starting X first to reinstall nVidia driver. Or keep the driver package on the PC eternally. That is the headache.

I'm not surprised some folks don't want to run new Linux OS.

Edit:
"to run the old xorg.conf starting X after update/upgrade kernel" - NOT always worked

resolution: 1680x1050
vertical: 56~76
horizontal: 30~98

if these are supported resolutions, you shouldn't have any graphics problem. did you try "nv" driver?

Yes, I have graphic problem. If changing to following settings;

Code:

 resolution: 1680x1050
vertical: 56~76
horizontal: 30~98

Xfce-4.2 can't start. I have to retain the old settings. But the screen resolution is "1280x1024". On adjusting font sizes on task top bar, screen fonts, etc. they did not work.

did you try "nv" driver?

On CentOS 4.4, NO. On other Linux OS, also on this box, such as slamd64, archlinux 0.8, FreeBSD 6.2, etc., YES. It did not work. Anyway I would try. Where can I have nv driver download?

# yum search "nv driver"

Code:

nv is a 'generic' driver for Nvidia and its pre-installed in all distros. check in /usr/lib/xorg/modules/drivers folder. you have to change Driver value in xorg,conf file only.

Code:

Section "Device"
        Identifier  "Videocard0"
        Driver      "nv"
        VendorName  "Videocard vendor"
        BoardName   "VESA driver (generic)"
EndSection

execute this to install correct Nvidia driver

Code:

yum -y install kmod-nvidia

its available in Livna repo.

Hi devils_casper,

According to your xorg.conf (check out the "Modes" list). 1680x1050 is not supported
(at least the xorg didn't think so ...)

You should try one of the resolution listed in your xorg.conf

or you can try to add the desire resolution into the "Modes" and force X11 to accept.

**devils casper** · 03-17-2007

did you try changing driver to "nv"? if 1600x1200 is supported by your Monitor then dont change it right now. try "nv" first.

**satimis** · 03-17-2007

Hi infwonder,

According to your xorg.conf (check out the "Modes" list). 1680x1050 is not supported
(at least the xorg didn't think so ...)

I tried already with following settings on the respective lines

Modes "1680x1050"
VertRefresh 56.0 - 76.0
HorizSync 30.0 - 98.0

The result was Xfce-4.2 failed to start.

You should try one of the resolution listed in your xorg.conf

or you can try to add the desire resolution into the "Modes" and force X11 to accept.

The screen is now displaying "1280 x 1024"

I'll leave it here. I fail to see any hope to get the problem fixed except download and install nvidia driver on nvidia.com. Then I'll face another risk of reinstalling nvidia driver after upgrade kernel and/or xorg.

The result of 64 bit Linux distro and 64 bit FreeBSD tested by me on last 3~4 weeks

1)
w/o nvidia driver problem
FC6, Ubentu

2)
having nvidia driver problem
CentOS, archlinux, Gentoo, slamd64, FreeBSD
FreeBSD is the worst, not only the vedio card having problem. The onboard NIC also has problem because of the nVidia chipset.

Edit:
Pls refers to;
http://www.nvnews.net/vbulletin/show...=41545&page=15
and
http://www.nvnews.net/vbulletin/showthread.php?t=82203

I also tested OpenBSD. It did not have nvidia driver problem on mobo (also on this box). I did not try graphic.

DragonflyBSD also has nvidia driver problem because it ports on FreeBSD.
