LinHES Forums :: View topic - SOLVED: Installing latest nvidia drivers on R5E50

Since the kernel source wasn't included with R5E50 by default, it has been a bit difficult to install any nvidia drivers other than 8776 and 7184. Thanks to the post at http://mysettopbox.tv/phpBB2/viewtopic.php?t=13281 we now know how to get the source. However, that's not the complete picture on how to get the latest and greatest drivers installed.

First, of course, follow the directions in the above post so that you have the /usr/src/linux-source-2.6.18-chw-13 directory. Now perform the following:

cd /usr/src/linux-headers-2.6.18-chw-13
cp -r . ../linux-source-2.6.18-chw-13

This merges the kernel-headers with the kernel-source, since the source by itself doesn't have the configuration files that were used.

Next, on my system at least, I had to at least partially make the kernel again, because certain kernel module scripts weren't in a usable state until you did that. So I did the following:

cd /usr/src/linux-source-2.6.18-chw-13
make
[wait about 20 seconds and then hit ctrl-c]

i ended up blowing away the install and starting over. Problem didnt happen this time so i dont know what went wrong. Works now thanks! the UI is so much faster now that the correct video drivers are there!

my ui is slow as well, but working. the xorg conf says i'm using driver nvidia though. if i did an upgrade do you think i have the correct nvidia drivers or should i try the above correct. (xorg seems to use up whatever cpu the frontend leaves)

Random, You didn't say anything about the hardware you're running.

If you upgrade the driver, I strongly suggest the change from this post: Lower x.org cpu load dramatically in R5E50 when watching HD http://mysettopbox.tv/phpBB2/viewtopic.php?t=13550

Excellent write-up. Thanks! this worked great and fixed a separate issue I was having.

Post subject:	why is nvidiadriver updating so difficult all of a sudden???
1. Why is nvidia driver updating so difficult in R5E50? It had no trouble updating drivers in R5C7 and R5D1. Is the difference with R5E50, the missing kernal source code? 2. Is it really necessary to delete the old nvidia drivers before downloading and installing the new ones? This was NOT necessary when I did it in R5C7 and R5D1.

You mentioned you had to make it again, so I'm not sure if that step is your "redo" or not. So do we do the make once, or twice (and the second time kill it after 20 seconds?) Or do we do it "once" and kill it after 20 seconds?

After a collosal failure (my Air2PC hdtv capture card stopped working) the first time I'm trying again. I read this to mean hit ctrl-c after 20 thus the make was never completed. All we have are some config files rebuilt and some object modules built but nothing that can stand on its own.

Made some progress. Got the same story. 1. Before NVIDIA update HDTV OTA works fine. 2. Update NVIDIA. Now I have no signal lock at all on all channes, and 0% signal. 3. Deleted Capture card and reinstalled, rescanned for Cable-High channels, now it works. Xorg on top is 30% cpu 4. Modify /etc/X11/xorg.conf with Option "UseEvents" "True", reboot, no signal lock again. 5. Repeat step 3. HDTV is back but Xorg is still 30%, hmm.

Have you enabled XvMC? Did you do the fix for the library location mentioned in the upgrade hints thread?

Author:	jmairs [ Sun Jan 28, 2007 11:06 am ]
Post subject:
Yes I corrected the link. Is there a way to tell what version of the driver is loaded? I tried grepping dmesg for nVidia but that didn't work.

Look in the X logfile... /var/log/Xorg.0.log BTW - There is an nvidia driver "update" task that runs at boot time which may need to be disabled, since it tends to keep forcing it's notion of the correct driver.
