Slackware 10 Laptop Problems
 
Hi I'm having a problem with the display drivers (I think). Erm rather I think the kernel isn't loading the correct modules for display. I have a 13" screen - and only about 4X7 is usable... I'm not sure whats wrong here - Its a Sony Vaio Laptop PCG-FX120. Running Slackware 10. -- Any help apprecated!

Not sure if this will help ... try setting the vga parameter in your lilo or grub.conf

vga=788 for example

Hello nocord

Are you saying that the GUI is using just a small part of your display, or is it your terminal display?

I have a PCG-GRZ530 running Slackware 10 (2.4.26) without any problem like that. And that is from a normal installation without and configuration. To get a higher screen resolution, some config was required.

nocord 09-09-2004 03:40 PM

Yes, the actual viewing area in terminal or X is like 4"X8" out of 13" monitor size. I've tried setting the vga in lilo.conf to "vga = normal" with no effect - It was previously set to "vga = 788" - what config do you mean guzzi?

ppuru 09-09-2004 11:39 PM

another suggestion ...
save the existing xorg.conf ... and try running the xorg config utilities

xorgcfg / xorgconfig

The config files that I modify to get a higher screen resolution are those in /etc/X11

Anything that has settings for my monitor I modify with the following:

Subsection "Display"
Depth 8
Modes "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 16
Modes "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
ViewPort 0 0

EndSubsection

However, I think that ppuru may be on to something with that last post. Or, is it possiable that the horizontal or vertical settings are in error?

Opps... Thats the settings from a server here, I'll get the SONY laptop settings an post them.

the /etc/X11/xorg.conf-vesa is the same. The /etc/X11/xorg.conf-fbdev has only one change from the above, and that is the line In Section "Device"

Driver "fbdev"

Hope this is will help for you.

Guuzi, can you

1. cp /etc/X11/xorg.conf /etc//X11/xorg.conf.orig
2. run xorgcfg

and try to reconfigure the display.

I just finished doing as you requested, and the file /etc/X11/xorg.conf that was created is similar to, but not identical to the inital file.

After running xorgcfg from /usr/X11/R6/bin, I started X and the display was at the resolution it had been, but the file needed tweeking. In the new xorg.conf I fixed the HorizSync from 31.5 - 92.0 to 30 - 110 Vert Refresh was OK at 48.0 - 170.0. And, I uncommented the Video Ram line which was correct.

My video card is a ATI 7000 AGP with 64M. I have the system see it as a generic ATI Radeon. The monitor is a Sony G420. I run this at 1600x1200 @ 85Hz

Have you any suggestions?

Cordless 09-11-2004 03:44 PM

I'm having similar problems - I think its something to do with the Vesa drivers - perhaps need to tweak them - any ideas as to what to tweak to???

please excuse my stupidity.

when I ran xorconf, I did it on a system other than the one we all discussing. The above post of mine shows the results from running xorgconf on a SuperMicro desktop system. On the Sony laptop, I don't have the xorgconf available anywhere in the filesystem to run.

Again please accept my appoligies for not keeping on the right track.

nocord 09-11-2004 09:15 PM

Hey guys got it fixed:

Turns out my graphics device was: "vesa" - I changed the driver to i810 and set the depth to 16 and it works great. Thanks for the replys!
