[SOLVED] Re: Intel GMA915 - Disappointing

Well. I was able to force the "Intel" driver and all does great except for "THE LARGE FONTS". No matter what I do that I know of to eliminate it, they stay. So, for now, I will wait a couple of weeks to see if they get it working. Otherwise, this will be a show stopper for me on using KK on this laptop.

Re: Intel GMA915 - Disappointing

But does compositing work with the 'forced' Intel driver? If 'yes,' please tell me what you did to 'force' the Intel driver?

Re: Intel GMA915 - Disappointing

Yes. Compositing appeared to work as my Panel bar was translucent the way I like. Under vesa that isn't the case. I used the below settings in "xorg.conf". Like I said, the system at least does parse the "xorg.conf" file properly and seems to use those settings.

The same Intel GPU worked flawlessly with Jaunty and earlier releases. Why did they have to 'break' it in Karmic!? Very disappointing.

When I bought my laptop a few years ago I chose it because of the intel grapics and chipset which at the time had very reliable linux drivers. Now they seem to have gone backwards. Hardware has always been a problem with linux but when it regresses like this it makes it impossible to choose even if you try to think of linux compatibility.

I had a similar experience with a usb wireless stick. I bought one based on a ralink chipset which had oss drivers and was hence recommended. I used it for 2 years and the drivers went backwards. It always amuses me when I see people on forums pronouncing that open source drivers are the solution to hardware on linux. I just don't see any evidence that there are enough developers with the skills necessary to develop drivers for hardware.

I will see how bad the karmic intel drivers are when I try on my laptop but I haven't yet decided whether to risk ext4. It is also disappointing to see a serious bug in such a crucial thing like the file system. Another example of something being introduced prematurely?

Re: Intel GMA915 - Disappointing

Actually I haven't had issues with ext4 after about a 3/4 year of use. That FS was developed properly based on what I read when following development.

What concerns me about ext4 is that there is a warning on the release notes about possible corruption of large files and a confirmed critical bug on the issue.

Re: Intel GMA915 - Disappointing

That may be why I never experienced anything. I don't usually deal with files over 512MB. The ones I do actually reside on a different FS. So if true, then my setup is what kept me safe.

Re: Intel GMA915 - Disappointing

GOT IT!!!!!!!!!!!!!!

Added "nomodeset" in the GRUB menu. Yes, I edited the grub.cfg manually. Added it to the end of the usual line. I also changed the xorg.cfg entry that had "vese" as the driver to "intel". Rebooted and I have the driver back. I still have the flicker at login, but that doesn't bother me since I have no flicker while logged in. Compositing works and my desktop looks wonderful! No lags in the system and performs a lot better than JJ. YEA!!!!!!!!!!!!

Re: [SOLVED] Intel GMA915 - Disappointing

Joined this thread a bit late but my Dell 630m Laptop with 915 graphics works pretty well. desktop effects work fine (except the cube!) and my test games (Torcs and Extreme Tux Racer) are very playable. Obviously frame rates improve if I turn off desktop effects first.

The flicker that was there with Jaunty and intrepid has gone - well in jaunty iirc that went with the 2.6.31 kernel.

FWIW my xorg.conf file is simply thus:

Section "Device"
Identifier "Configured Video Device"
Option "AccelMethod" "uxa"
Option "EXAOptimizeMigration" "true"
Option "MigrationHeuristic" "greedy"
Option "Tiling" "true" # i8xx users: see note in guide
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

Not late at all! Actually I added some of your Options in my xorg.conf. Didn't improve the logon flickering, but it didn't break my system after logging in. So, I guess I will keep the options. I find it weird that some Intel users don't have to go through the extremes as say me. I'm assuming it has to do with the BIOS for the most part on how the system reports itself.

he he like me heck my stuffs older I think

00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Integrated Graphics Controller (rev 04)

and the desktop effects are and have ben just fine sence JJ even the cube

I did try the intell tweks but emedeatley removed them in JJ but sence uping to KK no probs at all.

and my xorg.config is the default genaric blank template ...

Re: [SOLVED] Intel GMA915 - Disappointing

I wonder what will happen if I erase my Xorg.conf all together? Hmmmmm. Hold on! Time for a "break". Ha. Ha Ha.

**MoonRise** · Nov 02, 2009, 08:21 PM

Re: [SOLVED] Intel GMA915 - Disappointing

Well, it worked that way. Still have login screen flicker and have to have "nomodeset" in grub.cfg, but it appears the xorg.conf file isn't needed.

**vinnywright** · Nov 02, 2009, 08:25 PM

Re: [SOLVED] Intel GMA915 - Disappointing

ya I havent had one sence 8.04 ? I think......or mabey it wint that way with 9.04

Re: [SOLVED] Intel GMA915 - Disappointing

Hi MoonRise. Speaking of which, there's big bright moon coming up tonight over the mountains east of here.

re: manual edit of grub.cfg
I think when you get some updates, like new kernels, the grub.cfg will get regenerated; in fact, I'm under the impression that, for example, synaptic manages this service automatically. The manual edits will be gone. Anyway, if update-grub or grub-mkconfig ever runs, I'm pretty sure you'll lose the manual editing in grub.cfg. Might be best to set this under, I think, /etc/default/grub, in the kernel options section. Dave's done a good job covering that:
http://ubuntuforums.org/showthread.php?t=1195275

(Or, just file this info away in case it does break, then you'll have a possible remedy if ever needed.)
