I've looked all over the place for a solution. I've tried to reconfigure X and it doesn't EVER let me choose the driver any more. Is anybody else experiencing this same screen flicker with the Intel integrated GMA915 or other Display card? I really love II on this laptop (see sig below for details) but this flicker has really started to annoy me. I believe it is an X issue as it does the flickering with Desktop Effects on and off. I've verified what drivers are installed I just can't figure out how X is deciding which one to use! There is a lack of a place in KDE4 right now to change that. I've tried editing xorg.conf with what was originally there on older installs but it doesn't seem to read that file anymore. Anyone!!??

Re: Intel GMA915 and severe Screen Flicker
Yep. On my Nvidia GeForce 9600GT, when running with the VESA driver, it flickered once every 7 seconds. I was not sure whether I would get the Nvidia driver installed, or go nuts, first. :P
Once I got the proprietary driver installed, no more flickers.
Do you have the Intel driver installed yet? -
Re: Intel GMA915 and severe Screen Flicker
Yep...about every 7 to 12 seconds.
As far as I know it is. What command to check? From Adept, it says the Intel, i810, i740 and Poulsbo drivers are installed. Don't know if the last two are really needed, but that is what was installed by the installer, not me. Is there a tool similar to Envy for Intel?Comment

Re: Intel GMA915 and severe Screen Flicker
No, you can't go by Adept -- it shows half the drivers in the world installed! :P
Look at /etc/X11/xorg.conf. In "Driver" in the "Device" stanza, it needs to say "Intel".Comment

Re: Intel GMA915 and severe Screen Flicker
Just added that and rebooted. Still have the flickering. This is what xorg.conf looks like. Like I said, I've added to this file before and X doesn't seem to care about that file anymore. Ever since they started "auto-detecting" everything, changes I make to that file don't seem to take at all, laptop or desktop.
Code:Section "Device" Identifier "Configured Video Device" Driver "Intel" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" EndSection

Re: Intel GMA915 and severe Screen Flicker
Hmmm. Well, if Adept shows the driver "xserver-xorg-video-intel" is among those installed, then I dunno how to make it any better, Moon. I guess you could try afor fun, but I won't bet anything on it. :PCode:sudo dpkg-reconfigure -phigh xserver-xorg

Re: Intel GMA915 and severe Screen Flicker
One more notion -- you could try (with Adept) to remove the xserver-xorg-video-intel driver and install the i810 driver instead. It used to be recommended for that chip, but supposedly xserver-xorg-video-intel is the superseding driver. No change needed to the xorg.conf file -- it is still "Intel".Comment

Re: Intel GMA915 and severe Screen Flicker
Yep..Tried that already. I know it is X related. But it seems I'm the only one with the GMA915 with issues :P as I can't find a solution anywhere. At the moment anyway.Comment

Re: Intel GMA915 and severe Screen Flicker
It will not let me uninstall one with out the other being marked for removal as well. Is there no way of checking to see what Driver X automatically choose to use?Comment

Re: Intel GMA915 and severe Screen Flicker
Maybe the /var/log/Xorg.0.log? Just guessing .... :PComment

Re: Intel GMA915 and severe Screen Flicker
Well searching that I found this: (WW) intel(0): Bad V_BIOS checksum
Searched online and found quite a few people out there with that and with no real solution. It seemed to be tied with vRAM and BIOS shadowing, which isn't enabled on my machine, but the memory the card uses is dictated by the system BIOS. Also, it has no issues under other OSes like GG and HH. The flickering is really driving me nuts!!

Bummer -- possibly the changes to KDM involved with introducing KDE4 have brought this problem to light.Comment

Re: Intel GMA915 and severe Screen Flicker
More than likely. I have my Home on a separate partition. I'll just install over II and go from there. I don't see them getting this fixed any time soon if at all. HH ran well. I'll just install KDE4 that way.Comment

Re: Intel GMA915 and severe Screen Flicker
Well...I tried Ubuntu II 8.10 Beta Live-CD. No flickering there, and I even turned on all the Eye Candy their Live-CD would allow. Ran very smoothly. So is this an issue with kwin instead? I wish I knew how to report this. I get no error messages, and the one Warning I found in X-Org log is also in Ubuntu's. If I have to, I will install Ubuntu. There's no way I'm going back to the other
Plan on trying Kubuntu's beta Live-CD tomorrow and will report how it does there. Hopefully it has something to do with the original install.Comment

Re: Intel GMA915 and severe Screen Flicker
I suspect it is GDM versus KDM, and KDM is the bad boy that has the flicker bug. I wouldn't blame you for running Gnome for awhile, until the devs fix KDM.
