Intel Video troubleshooting/performance improvement link

Re: Intel Video troubleshooting/performance improvement link

I have to report a side benefit of upgrading to the 0.30 kernel.

My HDA Intel sound mixer dialog was modifed to show additional input sources and output sliders. Most importantly, is the stereo sound and Dolby 5.1 seems to work MUCH better, AND, now when I plug in a headphone the speakers shut off, and when I unplug the headphone the speakers turn on. In the past, for YEARS, I've had to use the mixer to mute/unmute the appropriate outputs.


Also, the control of Mic levels and the quality of sound are MUCH improved.

i wouldnt mind using the newer kernel except for 2 things;

- restricted drivers ? does it mean i will lose my wireless/ my wireless chip is a broadcom bcm 4312
- when KK is released, will we have issues upgrading ?
- lmilano -> where did u get .31 frm?

Re: Intel Video troubleshooting/performance improvement link

No, /proc/mtrr is not executable. You can leave it alone, it has the right permissions. The fixmtrr.sh script is pretty simple. It writes to the mtrr file with the following line:

echo "base=0x$address size=0x$hsize type=write-combining" >| /proc/mtrr && echo success

A permission denied would result if you can't write to /proc/mtrr.

ok. i have made fixmtrr.sh executable ( did this right frm the beginning) but it still cant write to /proc/mtrr?

Are you running it with sudo??

sudo /usr/local/bin/fixmtrr.sh

Also, can you pls show the output of

ls -l /usr/local/bin/fixmtrr.sh

?

- restricted: just try it out, install the restricted modules, and see if it works, the old kernel will still be there
- upgrading you can reboot to a jaunty kernel if you want to be ultra safe before the upgrade, just keep one around
- 2.6.31, the latest rc, is always in karmic

Note that this is ultrasafe, al long as you only install newer kernels. If the kernel upgrade depends on upgrading other stuff, please don't. That would be a recipe for disaster. So far that's not needed.

"ok. i have made fixmtrr.sh executable but it still cant write to /proc/mtrr?"

I don't run mine manually, no need really.

1. Navigate to System Settings/Advanced/Autostart
2. Click Add Script and make sure create symbolic link is checked in the dialog
4. Select the fixmtrr.sh script in /usr/local/bin if that's where you saved it.
3. Select Run On Startup

Done, no more running the script manually. If you do run it manually, use sudo as pointed out previously.

I've been running the script fixmtr.sh manually as well. I don't see how the above would work since the script has to be run as root/sudo and startkde (at least on my system) is run as the user. Is there something I'm missing?

I guess you could try using "kdesudo" instead if sudo. I just switched to gdm, but that would work I think. I just wasn't sure when exactly it should be run, so I followed the instructions exactly.

May be you can look into this post. http://kubuntuforums.net/forums/inde...4942#msg184942

I have been using that way for quite some time now. never had any problem so far with fixmttr and I dont need to run it manually too . You can always check whether it is running or not by trying to run it in konsole "sudo fixmttr.sh" If it is already running it will say "doing nothing, MTTR range already set up"

I also think you can set things to be run as "root" in the Autostart dialog, no? (not at my desktop now, to test)

Re: Intel Video troubleshooting/performance improvement link

Not on version 4.2.4. It might be worth it to run a test. I was wondering the same thing about the the user running the startkde process. I never ran it manually when I optimized. I just discovered my mtrr (intel 965GM) is correct and did not require the script to execute. It was never updating /proc/mtrr so I never hit the permission problem. If it proves not to work, create a new group on your system, change the group ownership on /proc/mtrr to the new group you created (sudo chown root:newgroup /proc/mtrr), make the file writable for the new group (sudo chmod 664 /proc/mtrr), then add your user to the new group. That should fix any KDE Autostart issues with permissions.

sudo /usr/local/bin/fixmtrr.sh

no, through autostart.

Also, can you pls show the output of

ls -l /usr/local/bin/fixmtrr.sh

?

-rwxr-xr-x 1 root root 1012 2009-05-01 06:43 /usr/local/bin/fixmtrr.sh
