The resolution I want does not appear in the GUI Display Preferences box, which only goes up to 1024 x 76. I tried to change it via Terminal with command: 'system-config-display', but get command not found. :-/

Has the command changed for 6.1?

In my experience when that happens it's because the auto-detection of the display resolution has failed. I simply worked around this by creating a good old /etc/X11/xorg.conf file manually.

IMHO there has been a regression in Xorg, I have been using the same monitors for the last 6 years and while up to two years ago auto-detection of the native resolution worked fine with all distros I tried, in more recent distros (not just SL) it doesn't work anymore (it defaults to 1024x768 as you say).

Ironically 'system-config-display' seems to have been removed since Xorg these days is supposed to autodetect everything and therefore work without a xorg.conf file... dry.gif

Thanks, the process looks straight-forward enough. Is there somewhere I can find the current auto-detected configs currently in use?

tux99,

I can create a xorg.conf file manually now, but I'm not sure how to change it. I want to believe I just have to enter the resolution I want somewhere, but should I assign settings to everything else there as well or just leave at defaults?

The xorg.conf file I generated is significantly longer than any I have googled, and includes information that does not appear in other versions. Can you advise on this, I'm worried that if I experiement I might not be able to access the machine and will have to reinstall yet again! Thus, I have become frozen in terror. sad.gif

Post your current xorg.conf and then we can advise you!

And post the make/model and native resolution of your monitor and the graphics card you are using too.

Ok, so I used the command...

It's got a lot of stuff in it as you can see, I'm sure I don't need to touch everything but I'm not sure what I do need to change. I'm also don't think my hardware acceleration is correctly detected (I can't run Minecraft for instance) but for now just changing resolution would be good.

What is still needed is the make and model of your monitor so that we can find out native resolution and horizontal and vertical frequencies supported.

Since you have an ATI card, you might want to use the ATI binary drivers (good packages are in the ELrepo repository) as those will give you 3D acceleration.

Ok, I have this old bad-boy: http://download.p4c.philips.com/files/4/4cm2299_22t/4cm2299_22t_dfu_eng.pdf

A 4cm2299/22t, it's a great big brutalist block of a thing, it makes me feel like I'm the navigator in the Millenium Falcon and that flat-screens are for salad-eaters and it gets the job done with only moderate to sever radiation exposure.. :-)

Try changing the monitor section to the following:

CODE
Section "Monitor"
      Identifier   "Monitor0"
      VendorName   "Philips"
      ModelName    "4CM2299"
       HorizSync    30.0 - 82.0
       VertRefresh  50.0 - 120.0
       Option "MaxClock"  "135000"
       DisplaySize 350 270
EndSection

And the screen section to:
CODE
Section "Screen"
      Identifier "Screen0"
      Device     "Card0"
      Monitor    "Monitor0"
      DefaultDepth     24
      SubSection "Display"
              Viewport   0 0
              Depth     24
              Modes    "1600x1200" "1280x1024" "1024x768"
      EndSubSection
EndSection


I don't think Xorg has built-in mode lines for 1600x1280, that's why I set the default mode to 1600x1200. Since it's a CRT this doesn't matter anyway as CRTs don't have a native mode like LCDs. You can cycle through the alternative modes ("1280x1024" and "1024x768") using Ctrl+Alt+Keypad-Plus and Ctrl+Alt+Keypad-Minus.

I edited the file as you suggested tux99, and dropped it into /etc/X11 as xorg.conf and rebooted, but no deal unfortunately. The highest option is still 1024 X 768. Is there something else I should do?

Here's the whole thing again with the changes...

Post the output of your /var/log/Xorg.0.log file. It's rather long so it's best if you put it on one of those text sharing sites (pastebin or similar).

Here you go...

http://pastebin.com/chwFfPgH

Might this be because I don't have ATi Radeon drivers installed? I tried installing them by following instructions on the Fedora site, I enabled EPEL and tried to install Catalyst drivers...
CODE

su
yum -y update


and then

CODE
yum -y install akmod-catalyst kmod-catalyst xorg-x11-drv-catalyst xorg-x11-drv-catalyst-devel xorg-x11-drv-catalyst-libs


however...

CODE
Loaded plugins: refresh-packagekit
Setting up Install Process
No package akmod-catalyst available.
No package kmod-catalyst available.
No package xorg-x11-drv-catalyst available.
No package xorg-x11-drv-catalyst-devel available.
No package xorg-x11-drv-catalyst-libs available.
Error: Nothing to do


I guess EPEL doesn't have these packages in afterall.

Add the following line to the Device section and then retry:

CODE
Option  "IgnoreEDID" "true"


If it still doesn't work then post the output of the log file again.

The binary driver for ATI is called fglrx in the EL6 Elrepo repo, but try the above first with the default driver included in SL6.

These are the ATI binary driver packages in ELrepo:
fglrx-x11-drv
kmod-fglrx

I will try that next and report back, and thanks by the way, I really appreciate your assistance and patience with all this. http://th166.photobucket.com/albums/u117/rdshear/Smiley%20Faces/th_smiley-face-thumbs-up.gif

No problem, my pleasure as long as you ultimately report back when it's working, nothing is more frustrating than helping someone who then doesn't report back that the suggested fix did solve the problem (unfortunately quite a few people do that sad.gif ).

No dice....

Pastebin: http://pastebin.com/4YcFa6Hc

I think IgnoreEDID doesn't work anymore.. there's a command apparently, I don't recall it now but it's a tool in xorg or something. Will sleep, work, google, and then return later with my findings.

I think at this point it's probably best if you try to install the binary drivers (fglrx-x11-drv and kmod-fglrx) from ELrepo.

xrandr is the tool I mentioned above, next I will try "gtf" and "xandr -S" command before installing the drivers.

Right, I managed to do it using gtf and xrandr following the steps detailed here:
http://www.arunviswanathan.com/node/53

and other pages discussing these two commands. To make it permanent the author in the linked page suggests adding the lines to /etc/profile.

Next, the ATi drivers. smile.gif

Well that seems like a crutch to me, I find it crazy that they disabled "IgnoreEDID" despite it's still showing in the man-page and despite it's essential in situations like this one. I fear the 'Idiocracy' virus is starting to affect more and more Linux programmers too... sad.gif

IgnoreEDID DOES work, I use it to Ignore the Monitors DPI info so I can fix it at 96, what he wants to do is use NoDCC but they killed it sad.gif

I installed the ATi drivers and that seems to have fixed things properly. Elrepo enabled, and then...

CODE
yum install fglrx-x11-drv kmod-fglrx


job done.smile.gif

Great. http://th166.photobucket.com/albums/u117/rdshear/Smiley%20Faces/th_smiley-face-thumbs-up.gif TBH I'm not too impressed with the current FOSS xorg drivers they seem to be getting worse rather than better (screen autodedection getting worse, manual overrides not working anymore), that's why I have been using only Nvidia (and recently ATI) binary drivers.
