How to turn off the GLX acceleration?
Dear Sir / Madam,
I need to use GView (a software for molecules visualization
constructed by Gaussian). An error occurs when I use the GView through
cygwin/X. "This error is that the GView appears in my desktop. However,
when I try to display a molecule, no molecule is observed in the window
of GView."
The Gaussian's reply is :
{{{ I see the following line in the setup,
> xorg-x11-xwin-gl (761 KiB; optional, the Cygwin/X X Server with
> ***EXPERIMENTAL*** GLX acceleration)
and the fact that GaussView starts but does not show molecules, which
require GLX while the splash screen and the basic dialog windows to
not, can be the problem. Can you turn off the experimental GLX
acceleration? }}}
How can I do it?
Regards,
Patrick Pang

Re: GLX acceleration
Lester, Exactly what kind of speedups are you expecting here? AFAIU, the GLX-accelerated XWin will give you speedup only for programs that use the GLX extension, which automatically excludes most standard X clients (e.g., xterm, emacs, etc). For applications not using the GLX extension, the GLX-accelerated XWin should be no different from the regular XWin. Alexander, please correct me if I'm wrong.

The dired problem is a cygwin DLL problem which should be fixed by today's snapshot: http://cygwin.com/snapshots.html . I don't know about the other problems. cgf

Re: GLX acceleration
Yes, XWin_GL seems to run OK, though I have not seen any dramatic speedup yet. It is likely that part of this may be due to memory problems I seem to be having in the latest xorg downloads, with XWin and now also with XWin_GL.

I cannot determine why, but with the new Cygwin base I just installed, a utility I have used for quite a few years, dired [http://www.math.utah.edu/~beebe/software/file-tools.html#dired], now freezes my window. A `top` shows that CPU usage quickly climbs to maximum values. I have to guess that other utilities will have similar problems. Thanks.

Just install it and run XWin_GL.exe instead of XWin.exe. Any feedback is welcome. BTW: Only the multiwindow mode is useful with the accelerated server since the OpenGL drawing surface is not translated to match the window boundaries in windowed moded. bye ago -- Alexander.Gottwald --8<-- bottom cut 2/2 <- top 2/2 --->8--

GLX acceleration?
In an effort to get better performance on my ThinkPad/XPPRo I'm considering adding the "experimental" GLX acceleration module offered under setup. Is anyone using this? How do you turn it on? Thanks. Lester

X Server GLX Acceleration Results
Hi, GLX acceleration works fine for me. Tried on Matrox G550 and ATI Rage Pro on Windows XP. glxgears shows a massive speed-up (gears graphic doesn't show on ATI?). More testing underway. Thanks Colin Harrison
