Guide to Get the Best Performace from the GMA 500

[blur xc]

hi, i' ve installed the jolicloud kernel and psb driver on ubuntu karmic, and it works very well. 1260 fps on glxgears.

i,ve added this repository:

deb http://apt.jolicloud.org robby main directory jolicloud

and then

sudo aptitude install -R jolicloud-poulsbo
sudo aptitude install -R linux-image-jolicloud linux-image-jolicloud-atom
sudo aptitude install -R poulsbo-config.

Really, 1260 fps? as in ~6000 frames in 5 seconds? What does this driver do that hte normal one doesn't?

so what your saying is the jolicloud graphics driver works better then the drivers weve been working with all this time?

Unfortunately performances are the same of the old driver stack.

Unfortunately performances are the same of the old driver stack.

the driver is the same, but is build directly on the kernel. from jolicloud blog:

Jolicloud believes that the DKMS approach to the GMA500 problem, which is fine for faster hardware, should not be necessary, especially on netbook hardware. Our goal was to integrate the Poulsbo drivers directly into the kernel itself, and support GMA500 out-of-the-box. Established conventions say that you must “decide” which DRI to use: either a Pouslbo-specific libdrm from v2.3.0, or something more recent. You couldn’t have both on the same system, right?
Users could now support 720p video, 1000+ frames per second in glxgears, no issues!

sudo aptitude install -R linux-image-jolicloud linux-image-jolicloud-atom
sudo aptitude install -R poulsbo-config.

instead of sudo aptitude install -R poulsbo-config

launch sudo /etc/jolicloud-netbook-config.d/poulsbo.sh

i.ve no tried with hd video, but the system with conpiz is most fluid.

Where did you get the public key for the jolicloud repository?

i use the repository without the public key. Is not a problem.

Have you had any crashes since installing evtouch? Every configuration of Ubuntu I have ever tested has crashed X on my T91 - but only when I am actively using the touchscreen and I believe this has happened to many other people on the T91 Installation thread. So, if you have not had any crashes so far, could you test your configuration by playing around in Gimp (or any other activity that actively uses the touchscreen) for a while and see if it crashes? Sometimes it has happened after only a few minutes, other times it take quite a bit of time to crash. Thanks.
P.S. I realize this is be a bit off topic, so it may be best to reply on the T91 Installation thread or via PM.

I had lock-ups of X after installing the poulsbo (gma500) driver, before installing evtouch. I've also had some lock-ups after installing evtouch. I haven't noticed any correlation between touch operations and lock-ups, but I'm not 100% sure of that.

However if I let the machine go into sleep mode, or if I actively put it into suspend or hibernate mode, at best it will come back into action with no cursor tracking of any sort (neither from the touchscreen nor from the touch pad). That's more troublesome.

Despite the lock-ups since installing the gma500 driver, I wouldn't go back, since the T91 is very responsive with that driver, and so laggy that it's almost unusable without it.

I haven't tried the gimp yet (I will later), but I tend to use the touchscreen a lot but haven't noticed a tendency to lock up then.

I did manage to confuse it and needed a reboot when using the touchscreen and the touchpad at the same time (unconsciously - I was resting my finger on the touchpad and realised I was trying to move the cursor with both hands). The cursor started going wild and jumping all over the screen before settling down. And then it looked like the calibration went off. But all was well after a reboot.

My mission in the next few hours is to get the screen rotation button and the brighten/dim buttons working. An elderly friend has decided the T91 (especially with Ubuntu NBR) is simple enough that he could use it, so I've just got the T91 he bought now set up the same as mine, and I'm giving it back to him in a couple of hours. (So I'm a bit pressed for time.)

Cheers,

Shoot. One must have a i386 install to run this. Jolicloud doesn't support lpia install...

W: Failed to fetch http://apt.jolicloud.org/dists/robby...ia/Packages.gz  404  Not Found [IP: 78.109.82.90 80]

Since jolicloud repository does not allow file listing (WHY?!?!?!), could someone please send me direct links to the required .debs? I'll try it anyway. Can't think of a reason why Jolicloud atom kernel wouldn't run on lpia distro.
