unable to view X in full res (only pans)

ixion · 07-29-2003, 08:13 AM

I cannot get X to run properly on an external monitor connected to my IBM Thinkpad laptop. I can startx, but the screen only shows 640x480 at a time. The actual desktop is 1024x768, and I can pan around it to see everything, but in all honesty, this is not a way to work.

These are the relevant sections of XF86Config:

Monitor(s)

Section "Monitor"

Identifier "Generic Monitor"

HorizSync 30-100
VertRefresh 60-160

EndSection

Section "Monitor"

Identifier "Laptop"
HorizSync 30-64
VertRefresh 60-75

EndSection

Device(s)

Section "Device"

Identifier "VESA"

Driver "vesa"

EndSection

Section "Device"
Identifier "RADEON"
Driver "radeon"
EndSection

Screen

Section "Screen"

Identifier "Screen 1"
Device "RADEON"
Monitor "Generic Monitor"

DefaultDepth 24

SubSection "Display"
Depth 24
Modes "1024x768" "800x600" "640x480"
ViewPort 0 0
Virtual 1024 768
EndSubsection

EndSection

edit: I'm using Fluxbox as my Window Manager.

Try control-alt-numpad+ or control-alt-numpad- to cycle through your resolutions, or remove the unwanted resolutions. My section:

Code:

Section "Screen"
        Identifier "Screen0"
        Device "NVIDIA GeForce 2 MX (generic)"
        Monitor "MAG 570V"
       	DefaultDepth 24
        Subsection "Display"
               	Depth 24
               	Modes "1024x768"
        EndSubSection
EndSection

I had actually already tried that, but tried again (both the Ctrl+Alt+numpad +/-, and restricting the res to 1024x768) to no avail.

btw, it also occurs in Enlightenment, so apparently it's not a fluxbox problem as I thought it was.

# Configuring X
Linux Hardware Compatibility HOWTO - video cards
The Linux XFree86 HOWTO
Common X configuring tools:
Debian - dpkg-reconfigure xserver-xfree86
Mandrake - XFdrake
Redhat 7.3 down - the setup utility leads to several config tools
Redhat 7.3 up - redhat-config-xfree86
You may have these tools:
XF86Setup
XFree86 -configure
Xconfigurator
xf86cfg
xf86config
xconf
ATI Linux drivers
If you need the nVidia driver, most likely, you want the Linux IA32 driver

how will those help this situation? I still need my laptop screen while on the road. There's got to be one setting somewhere in there that I don't know about so I can view full-screen with an external monitor. Is there something you see that's wrong with my XF86Config file? Here's the complete config:

I was suggesting trying other configuration tools you might have.

Try saving your config file with a different name and try some of the other configuring tools to see if you can get the resolution you want.

If you can't, rename the backup to the orig name and you are back where you started.

ixion · 07-29-2003, 08:54 AM

ok, I see what you mean..

actually I went with the VESA drivers instead of RADEON and the problem does not exist. It's got to be some setting with the RADEON kernel module. Oh well, I'm happy with VESA... this is a work laptop, so game playing is not really an option here anyway.

I mean NO FLAME in this, but it's just one more reason to not use Linux with ATI products. And since I'm a die hard linux'er, no ATI for me (when possible)..

edit: THANKS FOR YOUR HELP! :-D

You have to admit that they are much slower than nvidia with their Linux support.
