I also find it curious you are using 16 bit depth instead of 24.

Jenifer,
I see you have this in your /etc/X11/xorg.conf file:
Section "Module" Load "glx" EndSection
Others having the recent tksurfer problem should make sure they have these lines as well, as tksurfer uses glx.
Also, fyi, you can get a higher display resolution than the default. Try changing this line:
Modes "1024x768" "800x600" "640x480"to something like this:
Modes "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
It will use the first mode in the list, and if that doesnt work, it will try the next one. You can delete ones that dont work. In other words, put your desired resolution first in the list.

Hi Nick, I've attached the current /etc/X11/xorg.conf as a text file.
Let me know if I can provide any additional info
Cheers, Jenifer

Jenifer,
Thanks for the detailed info! Just to be clear, does your current /etc/X11/xorg.conf have the line:
Load "glx"
glx is OpenGL on X-Windows, allowing X windows apps, like tksurfer, to run using OpenGL, for accelerated graphics. Ideally, you want to load glx.

Not exactly sure how or what happened...but did manage to "fix" my tksurfer display problem. Since others on the list had reported similar problems, I thought I'd post what I did to "fix" the problem. Since I'm not a Linux guru, my "fix" is probably just a "bandaid"...but it did work...and hopefully the info provides some assistance to others.
Just to note the following particulars of my system: RHEL5 (DELL Precision 690n box went live April 16, 2008) Linux_x86_64 architecture
2 kernels: drwxr-xr-x 18 root root 4096 May 9 13:50 2.6.18-53.1.19.el5-x86_64 drwxr-xr-x 18 root root 4096 May 27 15:02 2.6.18-92.el5-x86_64
NVIDIA Quadro Fx 3450/4000 SDI Driver Version 1.0-9746
"Friendly" software also installed on the same box=fslv404 MATLAB r2008a is also installed (currently running -lgi on bert...I'll update on the outcome of this "friendliness" test)
As of yesterday, had several possible scenarios outlined:
- rpm -e dell-nvidia-rhel5-169.12-1dkms.x86_64.rpm rpm -ivh dell-nvidia-9746-7dkms.x86_64.rpm
--> should return to a well-behaved (albeit "older") nvidia driver...same as "out of the box"
- restore original "out of the box" settings for entire system via
/usr/var/dell/reinstall.sh --> should return ALL system settings to original "out of the box"...good for freesurfer and fsl apps but not so good for matlab...
- boot into older kernel (I apparently have a total of 2 listed in
/usr/src/kernels) [root@localhost kernels]# ls -l total 16 drwxr-xr-x 18 root root 4096 May 9 13:50 2.6.18-53.1.19.el5-x86_64 drwxr-xr-x 18 root root 4096 May 27 15:02 2.6.18-92.el5-x86_64
I attempted (1) first. However, the driver was not well-behaved for bert (tkmedit or tksurfer). I attempted (3) second. However, no change in behavior. While tarballing to prepare for (3)...since everything worked perfectly fine right out of the box -- before Matlab and before any package updates...I found my *original* /etc/X11/xorg.conf file (from April 16) and cp it into /etc/X11/xorg.conf & rebooted.
RESULTS: Was *very* happy to see tksurfer & tkmedit behave properly for bert. Proper behavior for tksurfer & tkmedit was observed in both kernels (after the xorg.conf file replacement). Still waiting to see if matlab behaves for bert's -lgi.
I diff'd the "original" xorg.conf with the "broken" one and the following lines were returned:
Hope this helps others find their "bandaid" solution to get them up and running again. Cheers, Jenifer
