Running current rawhide, with xorg drivers for my ATI card, I have xscreensaver + extras + glextras installed, regardless of whether I use xorg vesa drivers, xorg ati drivers or xorg ati drivers with EXA extensions I can't get any of the openGL screensavers to start they all give messages similar to ...
X error in glplanet: X Error of failed request: BadAlloc (insufficient resources for operation) Major opcode of failed request: 143 (GLX) Minor opcode of failed request: 3 (X_GLXCreateContext) Serial number of failed request: 111 Current serial number in output stream: 112
I was beginning to think this might only be expected to work with the ATI proprietary drivers, however yesterday I was tunneling X over SSH to my laptop running cygwin/X and I noticed that the openGL screensavers all worked that way (and with quite an impressive speed considering the tunnel was over WiFi)
Is it expecting too much of the current xorg drivers to support GLX (I thought MESA should at least step in as a software renderer as last resort) or should I bugzilla this?

Sorry to say that I won't be much help.
What ATI card?
I have not touched an ATI card since I purchased a new computer and got rid of the card 20 days later.
My experience says it will depend on the card and the version of the driver used. Search the archives as this has been discussed before. Contact ATI which will be a total waste of your time if my experience says anything.

It's a PCIe X550 based card, working OK with the stock xorg drivers for everything bar 3D, which in truth I don't particularly need, but I'm interested from a _testing_ point to view ...

I trust you found a suitable card, with suitable drivers for your needs, what did you settle on and what was important for you?

It's not a case of me asking for accelerated 3D support (either from the open source or closed binary drivers) more that I'm asking as a minimum shouldn't I get at software emulated 3D from mesa? As it stands everything from xscreensaver-gl-extras, to kinfocenter that even attempts to check for or use openGL gets refused ...
