unable to restore xorg resolution

This is a problem I have been having intermittantly for several years. I live in a rural area, where power interruptions are common.

When the power twitches, and X is displayed on the current tty. the display resolution is somehow lost.

When the system is rebooted and X restarted, the resolution displayed (and the best offered) is 800x600.

My resolution of choice is 1280x1024, and none of the configuration files appear to have been changed.

The X resolution is unaffected if another tty was displayed at the time. (I am often working on two or three consoles as well as what X is using)

In the past it has been sufficient to comb through the file system and delete all the temporary files and caches that seem to be associated with X.

I have never been sure if this was actually any sort of solution to begin with, but in any case it no longer seems to work.

I would suspect your graphics card in this case. I believe that is a dual monitor card. Do you have two monitors attached? I'm only guessing here, but I would try another card if you have one.

The Matrox card is working well, console framebuffers are unaffected, and the GUI is actually as good as it has ever been - except for the resolution.

Dmesg does not indicate any problems with the card or vram.

Yes it has two video ports, but I use only one for a 21" CRT. Using only the single port makes all the RAM on the card available to that port.

I am thinking the problem lies with hal/dbus/Xorg. Does a video card on the PCI bus (instead of a PCIE card) confuse one or all?

I am unsure where to look or how to poke at them in order to force the issue.

I am wondering whether there may be an issue with your monitor. When X is started it queries the EDID in your monitor and will only offer resolutions that the monitor says it can support.
Please post the contents of /var/log/Xorg.0.log and also the contents of your /etc/X11/xorg.conf

Also, have you checked the contents of /etc/X11/? I had a problem with a system (that I had upgraded many times) which still had a stale xf86config file in place that was being read when X started.

The monitor is an "NEC MultiSync XE21" and displays console framebuffers from boot at 1280x1024. I use this same monitor (via mechanical KVM) for other systems which so far are having no difficulty using it at that same resolution, although at the momnent only one is using GUI framebuffers at that resolution (the one using an o/s from ::shudder:: Redmond).

I have always had serious doubts whether this monitor is even capable of responding to queries of any sort. The horizontal and vertical sync rates (Hsync: 31 - 69 ; Vsync: 55 - 120) have never been properly detected by any operating system or application and have always required that I input those manually. In the past, X had a method for doing just that.

"/etc/X11" was one of the first directories I examined. I see nothing out of place there.

These are the pertinent entries from the config I had been using up to now.

The "Monitor section" was (I think) the work of "xorgsetup" from X as supplied by the previous (13.0) Slack release. The "Screen" section had to be modified to include the 1280x1024 resolutions.

Code:
...
Section "Monitor"
	#DisplaySize	  400   300	# mm
	Identifier   "Monitor0"
	VendorName   "NEC"
	ModelName    "533e"
	Option	    "DPMS"
EndSection
...
Section "Screen"
	Identifier "Screen0"
	Device     "Card0"
	Monitor    "Monitor0"
	DefaultDepth 24
	SubSection "Display"
		Viewport   0 0
                Modes "1280x1024" "1024x768" "800x600" "640x480"
		Depth     1
	EndSubSection
	SubSection "Display"
		Viewport   0 0
		Depth     4
                Modes "1280x1024" "1024x768" "800x600" "640x480"
	EndSubSection
	SubSection "Display"
		Viewport   0 0
		Depth     8
                Modes "1280x1024" "1024x768" "800x600" "640x480"
	EndSubSection
	SubSection "Display"

                Modes "1280x1024" "1024x768" "800x600" "640x480"
	EndSubSection
	SubSection "Display"

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

Try setting the horizontal sync and vertical refresh frequencies for your monitor by adding these lines to the Monitor section of your xorg.conf.
Code:
Section "Monitor"
	Identifier   "Monitor0"
	VendorName   "Monitor Vendor"
	ModelName    "Monitor Model"

That indeed seems to have solved that problem. I seem to recall trying to force those options in the past, but probably enclosed the values in quotes.

Many thanks

A few notes to conclude.

Initially I neglected to corect the "mode" entries in the "Screen" section of xorg.conf

Without defining the modes the GUI would start at 1680x1050 resolution, which is somewhat distorted on this 4:3 CRT.

Modifying the display resolution for each session was a minor inconvenience, however I also depend on being able to swithch out to a true console (Alt+Ctrl+Fn).

It appears that X must initialise with the same resolution (and colour depth ?) as are being used for the console framebuffers, otherwise the display may be hopelessly and possibly dangerously (for the CRT) thrashed.

It was necessary to restore the "Screen" section as described above.
Note these are all 4:3, not 16:9 widescreen aspects.

Code:
Section "Screen"
        Identifier "Screen0"
	Device     "Card0"
	Monitor    "Monitor0"
	DefaultDepth 24
	SubSection "Display"
		Viewport   0 0
                Modes "1280x1024" "1024x768" "800x600" "640x480"
		Depth     1
	EndSubSection

   ... ... ...
All is now working as expected.
