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:
1) 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"
2) 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...
3) boot into older kernel (I apparently have a total of 2 listed in
/usr/src/kernels)
[EMAIL PROTECTED] 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
