    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    Hello

    I use Kde4 and need to type: $ sudo fixmtrr.sh

    so I did the following thing:

    I mad a little C programme

    Code:
    #include <stdio.h>
    
    int main(void)
    {
    system("fixmtrr.sh");
    return 0;
    }
    saved it under : fixmtrr.c
    compile it:

    $ Developpement$ gcc -o fixmtrr fixmtrr.c

    then change owner to root
    give it the bit sticky
    give everyone the right to execute

    so this little programme can make "sudo fixmtrr.sh" without the sudo.
    then you can execute it automatically when KDE starts (in the control pannel)

    I don't know if anyone had find a solution for Kde I did not find the strenght to read 51 pages of messages...

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    Just a heads-up.

    After applying these changes on my Advent 6001 915GM laptop, performance was considerably worse.

    Then I noticed my user created during install had not been added to group 'video'.

    use "$ grep video /etc/group" to check you are in group video.

    use "$ sudo adduser <username> video" to add you if necessary.
    "Distros remove perfectly functioning programs and replace them with broken and insufficient replacements coupled with promises that the replacement will one day be just functional and stable as the prior working program"

    My user wasn't either in the video group. Which effect should this have had?

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    I tried the "safe/optimal" way by updating x and drivers and enabling uxa under kernel 2.6.28.11. I wanted to get rid of the tearing in videos on my Toshiba NB100 netbook but the result was worse than before. UNR was unusable sluggisch. After changing back to exa the netbook is usable again.

    Anyone an idea whats happening there? Upgrading the kernel seems not possible as theres no lpia kernel.

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    I updated an older system to Jaunty from 8.10. The graphics are not working. No application has a title bar, minimize, maxize, or close button; Totem will play a movie, just not display the video--only a black screen; terminal is a simple white square that cannot be typed in. Any advice?

    I just upgraded. Had to recompile ALSA (running a patch) but other than that no harm no foul.

    Prior to that, I experienced the font corruption yet again after my crummy battery discharged and sent my machine to hibernation. When I woke it up, Firefox and Thunderbird both had garbled text. Restarting X as others reported resolved the issue.

    I doubt that the kernel upgrade will do anything for the font corruption as I'm pretty sure this is more of an issue with X and the driver.

    Question Re: HOWTO: Jaunty Intel Graphics Performance Guide

    hey. Using the Simple option got my flash video working better.

    My computer has slowed down a little, and my touchpad is little more jerky (moreso when using small distances - but fine for major movements).

    I wanted to see if I need to tweak MTRR

    sarfarosh@sarfarosh:~$ cat /proc/mtrr

    Help would be appreciated

    Works for me only with the Bleeding Edge instructions - that is, requires kernel rc7, latest X.org drivers, and fixmtrr.sh script. But performance is, subjectively speaking, back up to Intrepid's standards. Thank you!

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    This seems to be solution I was looking for, since my 3d graphics run at about half the speed theyre supposed to. Id love to be able to update my graphics card, but Im new to ubuntu, and getting errors on Step one. I open the xorg conf. file and nothing is there in the terminal. It also opens up the file in a seperate window, but it is also blank. Do I not have any xorg files, and if so, where and how do I get them? Due to my ametur status with linux, half of the explanations on how to get the drivers installed I cant understand for the life of me. I apologise for any inconvience, but I need a bit of a down-to-earth explanation of how to get it to work.
