Video Problems for Precision 390

[Rogelio_Noriega at Dell.com]

Correction add swiotlb=65536 to grub.conf if you have 2Gb or more of ram
in the system.

A couple of questions.

1. what is the version of the nvidia driver and is it 32 or 64bit?
2. What error are you seeing when you try to build the driver from
source and do you have the kernel-headers rpm installed?
3. Do you have swiotlb=65536 option set in grub.conf if you don't added
it and reboot?

I hope this helps. 

Thanks Roger

I'm having 3 nagging video problems with my precision 390 running RHEL5:

1. After a period of inactivity, the display goes to sleep even though I
have the display sleeping disabled. The only way to get back in to the
machine is to type control-alt F1 and ctrl-alt-f7.

2. The corners of all windows show up looking squared off. Something
might be wrong with transparency?

3. When I open NVIDEA X Server Settings and click on OpenGL/GLX
Information, X immediately restarts and I end up back at the logon
screen.

None of these things happened when I used the Dell supplied version of
RHEL4 that came with the machine. Ever since I installed RHEL 5 I have
had these problems. I just used a generic version of the RHEL5
Workstation version, and then installed the latest dkms and NVIDIA
driver rpm from the linux.dell.com site.

Is there a better way for me to have a "Dell happy" version of RHEL5 on
here? We already pay for RHEL5 directly through RedHat so I don't want
to buy it from Dell.

Also, does Dell not officially support 32 bit RHEL? My choices for the
nvidia drivers have always been a 64 bit RPM or a source RPM that I
rebuild on my machine.

I tried to rebuild the src RPM that someone posted earlier in the week
but the rebuild is not successful.

Any suggestions on how to deal with these issues?

Thanks

-John
