[SOLVED] 1-Crash on KDE logout 2-KDE can't adjust resolution

[GetLinux]

1-Black screen on KDE logout

This happened before I made changes to xorg.conf.new, so nothing to do with the issue below.
This really stinks because after logging out of KDE (ending the session), the only way to shut down the computer is with the power button! How do I make it so lending a KDE session returns me to the shell?

I took a look at /var/log/Xorg.0.log and these are the only possible problems I found:

Some Additional Info (don't know if it's any help):

After reading up on graphics controllers and integrated video chipsets (mine is integrated), there are some more things I have learned about the specs of the Intel i810 Chipset, but I don't see anything that translates into changes I should make in xorg.conf. Here's some things about the 810 Chipset:

[GetLinux]

The changes to the HP site had me lost (many times you are taken to their shopping cart instead of info), but I tried one more time and was able to find this info on my monitor:

General:
Support for VGA, SVGA UVGA
Maximum non-interlaced resolution: 1024x768
15"/38.1cm
90 degrees deflection
0.28mm dot pitch
13.7"/34.8cm maximum diagonal visible image area
10.9"x8.1"/277mmx208mm maximum viewable area

Vertical Frequencies supported:
640x480 60Hz/31.5kHz
640x480 72Hz/37.8kHz
640x480 75Hz/37.5kHz
720x400 70Hz/31.5kHz
800x600 56Hz/35.2kHz
800x600 60Hz/37.8kHz
800x600 72Hz/48.1kHz
800x600 85Hz/53.7kHz
1024x768 60Hz/48.4kHz

I am confused about "Vertical Frequencies" in these specs, "VertRefresh" in /etc/vga/libvga.config and "check your monitor for vertical sync rages" in /etc/vga/libvga.config!

I think I can safely deduct that for HorizSync I should be entering the lowest frequency for the lowest resolution as the minimum and the highest frequency for the highest resolution for the maximum, hence "HorizXync 31.5 48.4". But the vertical terminology has me confused. My /etc/vga/libvga.config had "VertRefresh 50 90", and I had no idea where those numbers came from, or how any of the info on the HP spec page correlates to possible entries here!

Can someone please help me?
I haven't seen any answers or even and suggestions at all here, and I guess that's because a lot of you have built your own system, which I haven't. Has anyone here had to deal with this after converting an as-is Windows box to Linux?

A note about resolution and memory:

"Upgrading and Repairing PCs: 14th Edition" mentions minimum memory requirements for 2D operations as 2MB fir 1024x768 resolution with 16-bit color, or 4MB for 1024x768 with 24-bit color (true color)...which I know my monitor and chipset support. This would seem to verify that the VESA driver is not properly determining that the chipset uses UMA (I think).

I also tried to force VGA in /etc/vga/libvga.config, but that didn't work either....my monitor supports VGA, SVGA, etc. (as you can see in my above post).

I stopped at Barnes & Noble, and read some info from hardware chapters in many books. None of them gave me any more info, but one did specifically say that the i810 chipset is neither truly PCI nor AGP. This chipset supports 3D, too. Since the standard VESA driver (maybe) isn't working, I'll try forcing AGP and see if that works, my understanding is i810 emulates AGP although it's not.

Unless anyone knows of a specific workaround to make the VESA driver use system memory???

For what it's worth I have a similar problem. At the bottom of my post there's a reply with a link to an old forum question also with the same resolution problem.

What happens when you press 'ctrl-alt-F1' ? This should give you a console.
Also please post the video driver section of xorg.conf and any portion of /var/log/Xorg.0.log which shows an error (EE). Are you certain you are using the correct driver in xorg.conf for your hardware?

I don't know this for certain:
I believe that KDE will only show resolutions that exist in xorg.conf.

[GetLinux]

I put the resolutions in my xorg.conf, but I don't know if I need to change the VertSync or how to do so properly (see my above posts). I'm doing Bob P's way of rebuilding the toolchain right now, so I can't really do squat, but I'll post back with the info when I can. And maybe there was a build problem.

I have i810 (Intel) onboard video, and using the VESA driver, which as far as I know is supposed to be the only one that works with that chipset anyway (I could be wrong).

One thing I saw in another post is that you should not be logged in as root when doing your xorg.conf...why is that?

You should generally not be logged in as root. Higher security, less chance of doing something stupid by accident. However, changing system files is one thing that does require root access either through sudo or su.

[GetLinux]

Okay, after rebuilding the toolchain using:

[GetLinux]

Hardware: HP Pavillion XE 783 Desktop Computer
Celeron (Coppermine) Processor
Intel i810 Chipset (on-board video)
HP Pavillion V50 Monitor

My xorg.config:

[davidgurvich]

Off the top of my head the VertRefresh numbers seem completely wrong.
From what I see on the net the Pavilion V50 monitor is a 15" CRT monitor with 28 dot pitch.
The horizontal numbers seem ok.

The max. resolution is 1024x768@60Hz/48.4Khz
800x600@85Hz/53.7Khz.

First adjust those settings from your current 50-120.
Try these settings instead

HorizSync 28-50
VertRefresh 43-75

This was the log file, which was written on reboot after I posted my config file:
/var/log/Xorg.0.log

[davidgurvich]

It doesn't look to me like you have an X or kde problem there. I think you should start another post about the networking issues. Do you have PnP OS set to NO in your BIOS? You might try setting it to yes. Also, do you have ACPI enabled or disabled? If enabled in the kernel, you can disable when booting the kernel. If not enabled that might be your problem.

Also what kind of network card, and what modules are loaded?

[GetLinux]

Ok, I'll start a new post...but the funny thing is this only happened after changing my xorg.conf file...I think it's possibly there may be a memory overlap somewhere or something, because I've heard of that happening with some video cards. I've even seen it mentioned that you should turn off MTTR with some video cards, but I don't know if/why this would be needed and the consequences of turning it off.

Re: the PCI setting in my xorg.conf file:

[davidgurvich]

I've had problems with the combination of Realtek 8139 and nvidia video. I recall having to disable ACPI before it would work reliably with some kernels.

[GetLinux]

I'm using the i810 driver, not nvidia, but thanks...so it's interesting, then, to note, that video drivers can cause problems with your Ethernet. Nevertheless, since the original problems posted here are solved, see my new post in the "Networking & Security" section regarding my Ethernet card. I posted more input there, anything else I should post?
