[n] Slackware High Resolution Problem


Hi all,
I would like to set the resolution of 1152 X 864 with 24 bit color in Slackware 10.1...
I am using CA810E Intel Desktop board (onboard 82810 Graphics) and Samtron 75E 17" Monitor.

I am using 24bit 1152 x 864 with 75Hz refresh Rate in Windows 2000 Pro.

I tried setting in Xorg.config as per the post somewhere on this site but that resulted in black screen!!

Any idea?

1024 x 768 is too low for me!

Thanks.

Nirav

Log in as root, and go to /etc/X11. Make a backup of your working xorg.conf, and then run "xorgconfig". All lower case, no punctuation.

You may also need to get a driver for the card before it'll work in a non-VESA resolution. After 1024x768, the next resolution that VESA supported was 1600x1200, and I'm not even sure if the Linux VESA API will allow you to use that resolution at 24-bit, because I don't know if it'll address that much video memory.

You will also need to update the monitor settings so that X knows the monitor can handle it. If it knows the video card can handle a higher resolution, but thinks the monitor will croak with anything higher than 640x480, then it won't display anything higher than 640x480. There shouldn't be a big difference between 1152x864 and 1024x768, and my thought is that you may be getting a much lower resolution than 1024 because of the monitor settings.

xorgconfig will set the monitor up, too. Be sure to check http://www.monitorworld.com/monitors_home.html for your monitor so you know what to enter for the monitor.

A suggestion: Post the display section(s) from your xorg.conf file, and show us what you have that works, and what you tried that doesn't work. (The easiest way to post the file contents is to run a
Code:
$ cat /etc/X11/xorg.conf
command, select the text and copy it, and then past it into you post. If you start the pasted section with the \[CODE\] symbol, and end it with \[/CODE\] (without the back-slashes), it will look like the "cat" line above.)

Oh, if you use the "post reply" option (instead of the "Quick reply" box, just push the "Code" button, and paste it into the box.

The whole file is too large so I am posting/pasting whatever is important, I think!
Also, there is a difference between 1024 X 768 and 1152 X 864, try yourself, Though I can set resolution max up to 1280 X 1024 but that is with 60Hz refresh rate!! that's too flickery...
So, I want 1152 X 864 with 70/75 Hz.....
OK, here is my xorg.conf file

Code:

Did you try to replace all references to "1280x1024"
with "1152 X 864" and restart X ?

Also did you look at the output with :
cat Xorg.0.log | grep mode

...to see if there is not problem with "1152 X 864" setting

If I replace 1280 x 1024 with 1152 x 864 it directly goes to 1024 x 768 resolution! And Xorg.0.log is very large file with so many messages....!!!
Any other idea?

Thanks.

Reduce your

HorizSync 31.5 - 54
VertRefresh 60-90

your's is too high 160, gradually decrease the values and startx.

You can also do these steps:

1. run 'startx'
2. after your monitor goes blank press "CTRL+ALT+ PLUS KEY on the numpad"

3. now you can see the Display atleast
4. when you are in KDE or Gnome or XFCE
5. run 'krandrtray'
6. right click on the System Tray's Purple icon and choose your refresh rate etc.

have fun.

Hi,
That did not work
Ok, Let me ask this, if anybody using slackware 10.1 with resolution of 1152 x 864?

My hurdle is, I work with 1152 x 864 screen resolution in windows 2000 pro and my prev linux (Redhat 9.0), why slackware has a problem as it's NEW version.....
Is there anything to do with NEW Intel i810 gaphics driver that came with NEW Slackware 10.1? If RedHat 9.0 supports this reso, why can't Slackware 10.1, as drivers are from the same source freex86 project, isn't it?

I know, I am doing somthing wrong here, but couldn't find out what and where my settings are 'skewing'?
It would be nice if someone take me out of this problem...

Thanks.

change your default depth and put 1152x864 as the only option in Modes:

You might try using the gtf program to generate a modeline:
~> gtf 1152 864 75 -x

# 1152x864 @ 75.00 Hz (GTF) hsync: 67.65 kHz; pclk: 104.99 MHz
Modeline "1152x864_75.00" 104.99 1152 1224 1352 1552 864 865 868 902 -HSync +Vsync

This modeline is for my graphics card, but enter the same command. You may get better results if the system isn't loaded down much. Be sure you aren't exceeding the ratings for your monitor.
