[K12OSN] Can't get to the bottom of deep menus.

[Jim Christiansen]

Hi Jim,

Thanks for looking at my X troubles.  I just can't find any documentation on 
other XSERVER choices...  I'm thinking that this is probably the last place 
to look... I have tried all of the x_modes below found in the lts.conf file:

# 60 Hz Resolutions
#   X_MODE_0 = 640x480   25.175   640  656  752  800   480 490 492 525  
-hsync -vsync
#   X_MODE_0 = 800x600   40       800  840  968 1056   600 601 605 628  
+hsync +vsync
   X_MODE_0 = 1024x768  65      1024 1048 1184 1344   768 771 777 806  
-hsync -vsync

# 70 Hz Resolutions (Use instead of 72 Hz for 1024x768)
#   X_MODE_0 = 1024x768  75      1024 1048 1184 1328   768 771 777 806  
-hsync -vsync

# 72 Hz Resolutions
#   X_MODE_0 = 640x480   31.5     640  664  704  832   480 489 492 520  
-hsync -vsync
#   X_MODE_0 = 800x600   50       800  856  976 1040   600 637 643 666  
+hsync +vsync
#   X_MODE_0 = 1024x768  75      1024 1048 1192 1296   768 771 777 806  
-hsync -vsync

# 75 Hz Resolutions
#   X_MODE_0 = 800x600   49.5     800  816  896 1056   600 601 604 625  
+hsync +vsync

# 85 Hz Resolutions
#   X_MODE_0 = 800x600   60.75    800  864  928 1088   600 616 621 657  
-hsync -vsync

The 1024x768  65  mode uncommented above does work for 29 stations in one 
lab (as before), but no longer for all of our machines in our library 
(although it used to).

The only setting that I can get to work now is:

[lib03]
        XSERVER            = auto
# 60 Hz Resolutions
        X_MODE_0 = 800x600
#        X_MODE_0 = 1024x768  65      1024 1048 1184 1344   768 771 777 806  
-hsync -vsync
        X_MOUSE_PROTOCOL   = "IMPS/2"
        X_MOUSE_DEVICE     = "/dev/psaux"
#        Option      "Emulate3Buttons" "yes"
        LOCAL_APPS         = N
        USE_NFS_SWAP       = N
        SWAPFILE_SIZE      = 48m
        RUNLEVEL           = 5

I just can't find any documentation on other XSERVER choices...  I'm 
thinking that this is probably the last place to look...  The boxes in the 
library are ECS K7SEM mobos with pxe and integrated sis video.  Used to 
work...  Boy, I'm stumped and frustrated.

Thanks again,  Jim

My bet is you are really having a problem with the refresh rate and not
really the resolution.  I am guessing when you change to the higher
resolution you are simultaneously switching to a refresh rate that is
incompatible with your monitor.  I don't know much on where to change this
in X or exactly which file (hopefully someone else will pipe up with better
knowledge on this), but figure out how to use vi and where the needed files
are.  Then change your runlevel to 3 (I think this will boot to command
line), and play with your refresh rates until you find something that
works.  Then set the runlevel back to 5 (or whatever it was before messing
with it).

If this is with your clients try modifying lts.conf with different client
specific refresh rates and restarting the client until things take off.  I
usually have started lower say at 60hz then moved up until failure (higher
rate is usually easier on the eyes), and then stick with the last working
setting.

Good luck
