X server / GUI hangs

windycity_linux · 11-30-2006, 03:19 AM

I am using a Dell Poweredge SC430 to dual boot with win xp and redhat ES. I am having trouble after the installation to start the graphical mode (the screen gets disorted and the system hangs). I can use the text mode (INIT3) without any problem. but even from the text mode if i type startx the screen gets disorted and system hangs also.

I have ATI pci graphics card i believe 128mb, i have also an integrated video memory (but that is disables in bios).

new to linux - any help will be appreciated.

thanks

The system is probably not hung.. just the Graphical interface.
If you startx and it doesn' work you can try using CTRL+ALT+BACKSPACE to kill the X server and return to a Text prompt. that should help you avoid an uneccesary hard restart on the system.

sounds like a simple X configuration issue. most likely incorrect monitor settings.

http://www.redhat.com/docs/manuals/e.../s1-video.html

You could try redhats Configuration utility.. system-config-xfree86

A good piece of information to have on hand is the Horizontal and Vertical refresh rates for your monitor.. you can look these up in the owners manual or on the manufacturers website. if the refresh settings aren't correct you will get no usefull video.

i did try ctrl+alt+backspace but no respond (nothing happens). I have to hard restart.
Can i use system-config-xfree86 from text mode?
Also is there any way to adjust the screen resolution from text mode?

thanks for your help

sorry i posted befor checking the link. Now i know i can start a minimal X session from text mode using system-config-xfree86

windycity_linux · 12-01-2006, 03:02 AM

OK this is weird
I am getting the following error:
system-config-xfree86
-bash: system-config-xfree86: command not found

if I type system-config-display system hangs again. The screen is disorted and it does not respond to any command (including ctrl+alt+backspace)
I did edit the /etc/X11/xorg.conf file to use the resoulation 1024X768 but still the same problem.

however I did manage to startx on the system but this may not be the most appropriate method, i know my method is kinda crude, but here it goes any way:
i remotely logged on to the system from another pc using ssh. then i typed system-config-xfree86, but i got an error that command not found. then i typed system-config-display. I saw the display configuration interface came up on the trouble pc and I configured to use lower resolation 1024X768 and color depth to thousands of color. NOW the X start no problem.

I have copied the terminal below. any insight will be appreciated.

If decreasing the resolution and color depth got you an image then you should be set to go..

Did you check the Monitor refresh settings in xorg.conf as I suggested ?
I believe the monitor refresh rates are what causes most X configurations to fail.

Dunno what to tell you about the command not found.. as ytou can see by the link I provided I got that command right from RedHats docs.. Oh well.. guess when they switched from Xfree86 to Xorg they changed the command, heh

I prefer to just edit my X configurations manually at this point.. it just seems easier. and besides most times you REALLY need to fix a graphics problem is when it's not working and you can't use the GUI tools to adjust it anyway.

So everything is working now then I take it ?

If X fails for some reason, you can usually find useful information in the X logfile. This is usually in /var/log/Xorg.0.log (if there is one with 1 instead of 0, it is from the last-but-one run of X).

Errors start with (EE), warnings with (WW), and diagnostic messages with (II).

In my experience, X problems can sometimes cause the whole system lock up (press num and caps lock - if the LED indicators don't toggle, you're usually hosed). Whenever this has happened to me, it's been with the proprietary graphics drivers from Nvidia. I can only assume this is caused by bugs in their drivers. I don't have experience with the ATI drivers, so I can't speak to their reliability.

*sigh* I wish nvidia would open their drivers.

farslayer - yes every is working now

thank u all for ur help

windycity_linux · 12-05-2006, 03:23 PM

well the problem came back - i dont know what happened it worked by lowering the resoulation to 1024x768 for few times but now the machine locks up (pressing NUM or Caps Lock wont change the LED light) with a disorted screen and i have hard restart the machine. Also my montior (DELL 196FP LCD monitor) does not support 800x600 resoulation - thats the warning i am getting if i lower the resoulation to 800x600 and then i get a blank screen.

Just out of curiosity where did you get the low end refresh rates for your monitor ?
here are the rates for mine.. My LCD is not a dell, but notice the wider (lower) range of values on the horizontal refresh..

Code:

Section "Monitor"
        Identifier      "Generic Monitor"
        Option          "DPMS"
        HorizSync       30-82
        VertRefresh     50-76
EndSection

I see Dells lousy spec page doesn't bother to give you the Range for each value only the MAX value of each.. **sigh**

This is also probably the reason you can't get 800x600 to work, your horizontal refresh rate probably doesn't go low enough..

But if it works occasionally I would think something else is causing the X lockup issues.

I wonder if this message in your Log might indicate antything.. you could try commenting our DRI in the load modules section and see if it makes a difference

Also the native resolution for you montor is 1280x1024 so you may want to modify your config so you can run the screen at it's native resolution.. It tends to look best when it's not doing scaling and it displays one screen pixel on one LCD pixel.. imho

thanks for ur reply - with my sheer fraustation to get this thing working i was playing with /etc/X11/xorg.conf file thats when i remove the "dpm" option and change the HorizSync 60.0 - 81.0 from lower resoulation.

anyway it seems things are working (X is working fine) for now with commenting out DRI. may be that is the problem. I commmented out the DRI at "Section Module #Load dri" is that where I suppose to do or at the bottom of the page "Section "DRI" there?
And it is runnig at 1280x1024. Thanks again for your help.

here is the /etc/X11/xorg.conf file:
# XFree86 4 configuration created by pyxf86config

# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

# To customise the XKB settings to suit your keyboard, modify the

# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:

# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"

# If you'd like to switch the positions of your capslock and

Where you did it is correct.. it should ignore the section "DRI" at the bottom of the config because the module isn't being loaded..

Hope that's all it was !!

Have you tried 1280 x 1024 resolution yet ?

The reason I ask is that an LCD monitor is just like a piece of graph paper 1280 Pixels wide by 1024 Pixels high. by running in 1024x768 resolution you are splitting graphical pixels across hardware pixels and well hardware pixels don't resize.

Lets compare 1280x1024 and 1024x768 resolutions

1280/1024 = 1.25
1024/768 = 1.333

So every Graphical pixel is split across 1.25 Physical pixels horizontally and 1.33 pixels vertically.. which imho makes for an image that's not so crisp because an LCD just can't resize and split physical pixels between different colors. which is why I'm recommending for a sharp image you try the native resolution of the monitor.

your call.

yes i am using 1280x1024 resolution and it is working fine so far. Seems like unloading dri module solve the problem - well i hope so at least.

I had a similar problem after installing Mandriva 2007. My Dell LCD didn't like the resolution and refresh rate, and would hang after boot. My quick fix was to put in the install disk, pick update, cancel the update to get to the last install screen, then play with the monitor settings until one worked correctly.
