Penumbra Scrolling Graphics Problem

**msp301** · 08-05-2009, 08:35 PM

I've just installed the Penumbra Collection on my Jaunty 64-bit System using Intel X4500 graphics, I made sure I had all the 32-bit libraries on my system before starting install and then installed fine, but when I start any of the games, I get a scrolling picture constantly, otherwise everything else seems to work fine at the moment; has anyone else tried this with the same Intel card or is there a possible fix to apply to a 64-bit system??

Thanks again Smile

Well, I'm on Gentoo AMD64 using the Intel 2.8.0 driver with mesa 7.5 and kernel gentoo-sources 2.6.30-r5 (KMS enabled). I have quite some graphical glitches in Penumbra Overture (objects appearing and vanishing) but otherwise everything runs fine.
Currently, the Laptop is busy, later I'll check back after rebooting to Ubuntu Jaunty to see what's going on there.

You could try to lower the shader quality from high to medium

I tried now on Ubuntu 9.04 and the graphics are actually okay - a bit different compared to my desktop machine with the ATI card, but no problems of something scrolling or so, and it runs not very smooth with the 1280x800 resolution (not that I'm surprised - personally, I'm waiting for the ATI patch, I don't intent to play the game on the Laptop).

What I did compared to the original install: I replaced the libCg.so and libCgGL.so with the latest versions one can download from NVIDIA, and I moved most libraries out of the lib dir to use the system provided once. Remaining libraries provided by penumbra are
libalut.so.* libCGGL.so libCg.so libfltk.so.1.1 libopenal.so.*
Everything else is from the Ubuntu ia32-libs package.
Hope that helps.

Thanks for the comments, I've tried messing about with all the games' graphics settings, but it only alters the speed of of scroll (which it doesn't affect considerably) Sad

... how would I be able to find my Intel driver version on Jaunty, tried searching everywhere without luck as I bought my laptop with 9.04 already set up Smile

apt-cache policy xserver-xorg-video-intel
for me it gives 2:2.63-0ubuntu9.3

Linux kernel version:
cat /proc/version
2.6.28-14-generic

you can also look at /var/log/Xorg.0.log (I've attached mine, so you can compare)

my xorg.conf is empty in Ubuntu, so xorg probes everything itself, I don't run compiz.

Ok, thanks for your help, I've messed about and killed compiz, but lost the ability to run Overture Sad

... will try a reinstall as both Black Plague & Requiem seem to be running fine ... as I still want to have compiz for general desktop use, is there a way that when the game is launched it could turn compiz off, but then back on when I quit the game ?? Thanks again for your help, this could confirm that theb X4500 can work as well as the X3100 Smile

you could modify the launcher scripts in the game install directory (/usr/local/games/PenumbraCollection/Overture/penumbra or ......../PenumbraCollection/BlackPlague/blackplague and ...../BlackPlague/Requiem )

and have them stop compiz before running the game and re-start it afterwards..

something like

Code: (Select All)

metacity --replace &

......  regular script to launch game .....

compiz --replace &

It's not elegant and not tested:-D

Hey, thanks, but yeah I've already tried that, using the script below, but it stops the game from launching for some reason, it's as if the game starts, but is then interrupted by compiz restarting :S

Code: (Select All)

#!/bin/bash

metacity --replace &

cd /usr/games/PenumbraCollection/Overture/penumbra

./penumbra

compiz --replace &

Maybe you should wait a little until metacity has indeed replaced compiz:
#!/bin/bash
metacity --replace &
sleep 2
cd /usr/games/PenumbraCollection/Overture/penumbra
./penumbra
compiz --replace &
