Intel X4500HD slow Performance no Hardware Acceleration

Psikon · 2010-06-21 19:17:07

Hello everybody,

I am relativly new to the Arch users. after some time using ubuntu i tried to test a "real" linux for my laptop. So i startet with installing gentoo. But after realising that i am to stupid to even get the installation complete, I tried out Arch Linux and it runs really fine. But i have still a problem with my graphic card. I am using a Lenovo Thinkpad T400 with an Intel X4500HD and a Radeon X3450. Because there is no real support for switchable Graphics i am using only the intel one. My Problem is, that i have no real real 3D Performance with it. Under ubuntu i could play some games with wine for example Civilization4 or Warcraft 3 TFT and some Linux Games based on opengl like alien arena or so on, but under Arch Linux i have many lags even at the beginning in the menus. I have searched everywhere, but i could not find any suitable solution. For everybody who has an idea i have some facts to my system. If there is anything missing pls tell me what, maybe with the right commando, because a am a little bit new in the linux community.

First i tried to edit my Xorg.conf file. but there was no change after reboot. i add some options like UXA or EXA and DRI but nothing happens. after that I tried to look if KMS is active or the problem, but i found nothing that would explain my problem. My last idea was that this xf86-video-intel driver has no 3D Acceleration and I must used the one from the intel website to activate it. Is that right or comes the problem from other mistakes i had done?

Thank you for your help.

After todays upgrade of xorg, mesa, xf86-video-intel I'm experiencing slow video performance on my Intel X3100 too.

xorg-server 1.8.1.902-1
mesa 7.8.2-1
xf86-video-intel 2.11.0-2
intel-dri 7.8.2-1

glxgears shows me the following:

Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
299 frames in 5.0 seconds = 59.661 FPS
300 frames in 5.0 seconds = 59.942 FPS
300 frames in 5.0 seconds = 59.946 FPS
300 frames in 5.0 seconds = 59.958 FPS

Games such as Assault cube, Extreme Tux Racer, Hedgewars run much slower than before.

So do I need to configure something to improve my video performance or it is just another bug with intel video?

takedown · 2010-06-21 23:32:59

same here, but my system run normaly... I think glxgears output isn't a real parameter

Psikon · 2010-06-22 09:42:26

Look at the values of glxgears. It runs with vertical ync. If you have an TFT Monitor with 60 Hz it cannot run faster because it is limited to the refreshrate. after the update my glxgears runs also with vsync. i dont know why. If you have a soluton for the vsync problem pls post here.

priit · 2010-06-22 23:45:59

I've got the same configuration as Psikon and also getting sluggish perfomance when Compiz enabled. Was just fine before the upgrade ... I've done a complete reinstall (different reasons). Only error in Xorg.log is
[ 84.664] (EE) Failed to load module "fbdev" (module does not exist, 0)

takedown · 2010-06-23 00:15:04

I hace the same error about fbdev but I really don't know why...

KlavKalashj · 2010-06-23 00:28:13

remove your xorg.conf, I have the same card and works fine without.

Edit: rename/backup/move, that is

Tried that first, no difference.

VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller

Same here, slow with Kde after upgrade ...

priit · 2010-06-23 09:56:32

My problems dissapeared for now when I enabled Loose Binding and Indirect Rendering in Compiz.

Psikon · 2010-06-23 10:39:23

I am using metacity, beacause compiz need so much performance on battery. The idea to delete had i also yesterday. But after doing it there was no difference.

Psikon · 2010-06-23 14:16:02

A generallary question from me is. Is the xf86-video-intel driver from the repos the same like the one from the intel website. or does this driver has special features like 3D Acceleration, that can solve my problem?

Renan Birck · 2010-06-23 17:56:50

Regarding slowdown of X after latest upgrades, I have the same problem. Games like Neverball (which used to run decently) are extremely slow after xf86-video-intel 2.11.0.

I have an Intel X3100 on Acer Aspire 7720 laptop.

They are the same.

Psikon · 2010-06-23 23:15:20

But i have the problem longer then the last upgrade. it runs the last half year with this slow performance.

Psikon · 2010-06-27 21:39:23

Has nobody a solution for this problem?

dominikh · 2010-06-29 22:51:02

Yeah, same problem here, extremely bad OpenGL performance. Even glxgears causes one of my CPU cores to use 100%.

Furthermore, Lincity-ng is an interesting example. using GL (the default), even the menu is darn slow, the game pretty much unplayable. But if I switch to SDL instead, the game runs smoothly.

Psikon · 2010-06-30 22:32:26

Not testet this example, but you provide me testing cairo dock with OpenGL. It is really unusable. Under Ubuntu i had never a problem with that. do you think that the problem will solve themselve with newer intel driver or x org files or is it not well configurated by myself?

Roline · 2010-07-01 08:25:41

I have the same problems, also with flashes (when using > xf86-video-intel-1.9). So I downgraded to 1.9. Tho this didn't fix a lot, it did fix the flashes.

pascal16 · 2010-07-01 19:50:36

I have the same problem with an Asus UL30VT using the xf86-video-intel 2.11.0-2 driver that was installed yesterday during a sysupgrade. The screen refresh rate became so slow that my system was almost unusable, but after running Compiz with Indirect Rendering and Loose Binding enabled things improved a lot. It still seems that video performance is much slower than before though, so I hope a fix is released soon.

pascal16 · 2010-07-01 20:06:28

Updating to xf86-video-intel-newest from AUR (version 2.12.0-1) fixes the problem!

Post other configs plz!

Psikon · 2010-07-02 10:31:07

I have tried the newest driver from aur. it change nothing for me. I am nor sure if me problem causes only from the driver. I wonder about the output of glxinfo at the end:

It is always saying the same up from the beginning of my arch installation. I dont know where this output come from, but must there stand other things then slow and none? What says this output in detail?

Way more interesting is the question if everyone who suffers from slow performance actually configured his system properly. Specifically, if `glxinfo |grep -i "opengl renderer"` returns "software rasterizer", you're not using hardware acceleration. That's most likely because you forgot to add your user to the "video" group, which is necessary for access to the DRI device (/dev/dri/card*). The obvious check here is `groups | grep video` and the obvious fix is `gpasswd -a $USER video`, followed by logging out and in again.

Maybe this already helps some people.

I have added my user to the video group but `glxinfo |grep -i "opengl renderer"` still returns "software rasterizer"... Any more options?

Did you log out and log in again? And what does `ls -l /dev/dri/card*` say?
