Default 1 fps with 1.3.52 driver

Running glxgears gives me 1 fps with the new 1.3.52 driver and evdi 1.3.43.

I've also noticed that dmesg has a lot of those:
"evdi: [W] collapse_dirty_rects:102 Not enough space for clip rects! Rects will be collapsed"

The performance is very bad, no matter if I use the xf86-video-intel or glamor.

How to increase the performance?

Have you tried modesetting instead of intel? From what I know the intel Xf86 driver is deprecated.

Also, if you must use intel, try adding "Option" "DRI" "2" to the xorg.conf section for the intel driver, that worked for me.

The intel driver works much better for me. Glamor is increadibly slow compared to the intel driver on my system, so that's why I switched back to intel.

The performance of the new displaylink driver and the newer evdi release is much better than in the previous one, but still a bad joke in comparison to how the device works when I use Windows (which I do maybe 1 hour / year - so it's not really helpful).
It's a pity that Displaylink doesn't provide the source code. I would love to work on that project. :/

Why are you using DRI 2, not DRI 3?
