I just installed Redhat 9.0 Professional on my laptop, (HP Pavilion XH136 - 600 MHz Celeron, 10.0 Gig HD, 192 RAM, S3 Savage IX video).

I have tried and tried to adjust the screen resolution past 800x600 (the native resolution for my screen in windows is 1024x768).

I have used the configuration utility by going to the Red Hat, then system settings, display and changing the resolution. It says to log out, restart X, then log back in.

I have logged out, and went as far as restarting the PC but, there has been NO change in resolution. When I go back into display settings, it is still at 800x600.

I am very new to Linux. Can anyone help me? I cannot take this 800x600!!!

Thanks!

ok in your file /etc/X11/XF86Config is 1024x768 listed in your screen modes resolutions, for instance mine says:
SubSection "Display"
Depth 16
Modes "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection

No, mine is this:


Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Unprobed Monitor"
DisplaySize 10 7
HorizSync 31.5 - 37.9
VertRefresh 50.0 - 70.0
Option "dpms"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "savage"
VendorName "Videocard vendor"
BoardName "S3 Savage/IX"
VideoRam 4096
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "800x600" "640x480"
EndSubSection

Can I add "1024x768" in there under modes???

yes you can....make sure your logged in as root for you can save your changes, and just add "1024x768" on that line....

so it looks like:
Modes "1024x768" "800x600" "640x480"

Okay, tried that, but, the setting will not "stay".

Does the video memory have something to do with why it won't work"

Thanks for the help so far.

the changes don't stay in the file when your logged as root ? and the video memory shouldn't have anything to do with it technically but how much do you have and what does it say? cause if you say it goes 1024 in win, then it will in linux, theres no doubt about that...maybe you have the wrong video driver or something, umm post more details and i will try some more ideas.

The video device is S3 SavageIX, identified the very same way in the Windows Device Manager. There is 4 Megs of Video Ram just as shown in the part of the config file shown above.

Everytime I tried to add the 1024x768 to the file, it would disappear the next time I booted. The screen did look bigger, so I think it did do something. However, my goal was to make the screen as big in Linux as it was in Windows. I want the image to take in the whole screen area.

Also, since I was trying to adjust the video size, OpenOffice stoped working properly. Whenever I tried to run it, the only thing that would show on the screen was the word File, and it took in the whole screen that was visible.

For now, I have reverted back to Windows on this laptop, and am going to experiment with Redhat 9.0 Prof on another machine that I have.

I do appreciate the help.

I just had this same problem...
Go to the redhat-config-xfree86 gui, and go to the advanced tab, and then choose a generic monitor that fits your hardware. I have an hp pavilion n5190 and it worked witht the "generic Laptop Display Panel 1024 x 768" I was following all of the steps pther people are recomending, and none of 'em worked.

Maybe first do:
su
init 3
redhat-config-xfree86 -v --reconfig
(that causes the config program to ignore previous settings and do its best from probes)
then when you get out of there,
init 5

--then do the cahnge I mentioned above, restarting the X server each time you mnake a change to test it out.
hope this helps, it did for me.

Also check that the horizontal and vertical refresh rates of your monitor are set correctly. If not they will be limiting you to what resolutions will work correctly.

I had a sync problem some time ago. You need to find out the recommended Vertical Refresh Rates (usually in the documentation) and the corresponding Horizontal Sync Rates. For example, my monitor, though LCD has an analogue input so appears to the system as a normal CRT monitor. At 1280x1024 res, its optimum V Refresh is 75.3Hz. The corresponding Horizontal Sync is 80.3kHz. When I first checked XFree86 the Horiz Sync line was something like

HorizSync 31-79

This means that the computer would not sync it at 80.3 which rendered the Vertical Refresh rate at 75Hz unusable. Instead it used 60Hz which gave a poor, fuzzy display. I changed it to

HorizSync 31-81

and all was well.

Perhaps you have documents which give the necessary figure or can find out from the manufacturers Web Site.

Well did it work? I'm about to embark on the same mission to install either Red Hat 8.x or 9 on my HP Pavilion N5190.
