Fedora 7 stuck on 640x480 Screen Resolution

Chargh · 08-30-2007, 11:00 AM

I went to bed, and When I woke up I saw the resolution changed. My farther was using the vmware win xp pro virtual machine at the time. It used to be 1024x768, but now I can only use 640x480.

Try xrandr

Code:

xrandr -q

Should output something similar to this

SZ:    Pixels          Physical       Refresh
 0   1600 x 1200   ( 363mm x 272mm )   75
 1   1280 x 1024   ( 363mm x 272mm )  *85
 2   1024 x 768    ( 363mm x 272mm )   85
 3    800 x 600    ( 363mm x 272mm )   85
*4    640 x 480    ( 363mm x 272mm )   85
Current rotation - normal
Current reflection - none
Rotations possible - normal
Reflections possible - none

Now change it to whatever you had
Example for 1024 x 768

Code:

xrandr -s 2

This is really cool method of doing it. I had messed up xorg.conf & had a screwed display. Thanks to your tip, i now have decent display in linux. If this thing works across distros then i can improve display in my ubuntu pc.

It did not work.

[Hamish@localhost ~]$ xrandr -q
Screen 0: minimum 320 x 175, current 640 x 480, maximum 640 x 480
default connected 640x480+0+0 0mm x 0mm

640x400 85.0
640x360 85.0 75.0 70.0 60.0
640x350 85.0

Looks like you have an xorg.conf issue. Can you post your /etc/X11/xorg.conf file. Also you monitor specs and video card

Well heres xorg.conf:

# Xorg configuration created by system-config-display

Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "radeon"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "640x480"
EndSubSection
EndSection

Edit this line

Code:

Modes "640x480"

To Something like

Code:

Modes   "1280x1024" "1024x768" "800x600" "640x480"

Then do a

Code:

Ctrl + Alt Backspace

to restart the X-Server. Log back in and see if the default resolution is higher. If not then you should be able to use the "xrandr" trick to make the default whatever you want based on what you edited in the xorg.conf file

so xrandr -q should display all the resolutions you put in xorg.conf

0 1280 x 1024 ( 363mm x 272mm ) *85
1 1024 x 768 ( 363mm x 272mm ) 85
2 800 x 600 ( 363mm x 272mm ) 85
*3 640 x 480 ( 363mm x 272mm ) 85

The "*" is the default resolution

Now you should be able to

Code:

xrandr -s 1

or

Code:

xrandr -s 1024x768

It is fixed, just in time for School. Thanks everyone.

Erik765 · 10-30-2007, 01:02 PM

I'm having the same issues and I edited xorg.conf to add the higher resolutions.
It now looks exactly the same as the previously posted xorg with more modes.

When I do the xrandr it only displays 800x600, 640x480, and 400x300.

I have in my xorg.conf "1152x864" "1024x768" "800x600" "640x480".

I tried to force it with xrandr -s 1024x768 with no luck.

Also the refresh rate in the control center says I can only use 56 and 60. I know this monitor is capable of at least 1280x1024. I use that in Wi***ws. Any other ideas what else could be causing the problem here or what else I could try?

Thanks for you help.

Looking for some help. Installed Fedora 7 for the 3rd time. The 2nd and 3rd time the resolution is stuck at 800x600 and I have the option of 640x480. I am trying to fix this but have not figured out how yet. Here's my xorg.conf file:

# Xorg configuration created by pyxf86config

Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "radeon"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection

I have tried a few things like xrandr -q but from all I can tell that is informational only. What is a good line or .conf editor? Any help will be appreciated. Thanks.

You need a monitor section specifying your horizontal sync and vertical refresh. Then please read this post above as it tells you that you need to add "Modes" to your Screen section. You can google the model number of your monitor to find those values. You'll need to find "horizsync" and "vertrefresh". Please do not use my values below, they could damage your monitor if unsupported.

Here is my section (THE VALUES WILL NOT WORK FOR YOU. FIND YOUR SPECIFIC VALUES)
Section "Monitor"
Identifier "Monitor1"
VendorName "Monitor Vendor"
ModelName "Dell M110"
HorizSync 30.0 - 107.0
VertRefresh 50.0 - 160.0
Option "dpms"
EndSection

What to do if installing it on VM (under VmWare on Windows)?
In most cases I need only putty access but sometimes prefer to work in GUI. But by default it installed in 800x600 resolution and supports only 800x600, 640x480.

After I added your "Monitor" section I got a message that screen is absent and "startx" did not work. So I removed it.
And seems there is no GUI to edit such settings. :-(

Any ideas how to make it running in 1024x768?
If possible without terribly deep and wide reconfigurations...
