RHEL-4 display problem for philips 150S LCD monitor
 
Hi,
I am unable to do the setting of my display in 1024X768 for linux (RHEL-AS -4) only.For any windows os its working perfectly.I have done all the display settings from frontend and from backend i mean file /etc/X11/xorg.conf.but its not working.
It was working previously.Please help me regarding this as "800X600" resolution is very bad.


The details are as follows:

monitor : philips 150S -15 inch
OS : RHEL-4
videocard : Intel 810
cpu : Intel 845

As root simply (your choice of text editor) edit the /etc/X11/xorg.conf file and add the resolution, sample section of the file below;

Code:

Section "Screen"
        Identifier "Screen0"
        Device    "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth    24
        SubSection "Display"
                Viewport  0 0
                Depth    16
                Modes    "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Viewport  0 0
                Depth    24
                Modes    "1024x768" "800x600" "640x480"
        EndSubSection
EndSection


Or you could from runlevel 3 (init 3) as root type something like;

system-config-display --reconfigure --set resloution 1024x768 --set depth 24

but its not working.I have checked all options but its of no use.I think Intel VGA onBoard video drivers is not supporting or KErnel is not supporting.One case is that drivers are needed for kernel version 2.6.9-EL which is not available on net.

Questions:
1. What hardware do you have???
2. Which kernel exactly???
3. What version of the xorg rpms are installed???
4. What does your /etc/x11/xorg.conf file look like??

The commands to help you answer the quiestions:

/sbin/lspci -v
/bin/rpm -qa --qf="%{n}-%{v}-%{r}.%{arch}.rpm\n" 'kernel*' 'xorg-x11*' | sort
/bin/cat /etc/x11/xorg.conf

Since this is an on-board video card increase the shared video memory to the largest value possible (at least 16/32 Megs) and edit the /etc/xorg.conf;

Code:

Section "Screen"
        Identifier "Screen0"
        Device    "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth    16
        SubSection "Display"
                Viewport  0 0
                Depth    16
                Modes    "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Viewport  0 0
                Depth    8
                Modes    "1024x768" "800x600" "640x480"
        EndSubSection
EndSection

I know it's terrible form to dig up old threads, but I had to say "thanks" for the tip. I had a RHEL workstation with xorg not playing nice and this was the problem. This fix saved me from a prolonged headache.
