Subject: rss-glx: screensavers consume 100% CPU

Date: Thu, 04 Oct 2007 02:15:55 +0200

Package: rss-glx
Version: 0.8.1-6+b1
Severity: normal


Every time I turn on any of the screen savers in this package
it uses 100% CPU, or at least 100% of one core (I have 4). This
is double-weird because I have an NVidia based card with all
the binary drivers installed.

glxinfo(1) and glewinfo(1) seem to suggest OpenGL is set up ok:

$ glxinfo
name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
server glx extensions:
    GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_SGIX_fbconfig,
    GLX_SGIX_pbuffer, GLX_SGI_video_sync, GLX_SGI_swap_control,
    GLX_EXT_texture_from_pixmap, GLX_ARB_multisample, GLX_NV_float_buffer,
    GLX_ARB_fbconfig_float, GLX_EXT_framebuffer_sRGB
[snipped]

$ glewinfo
---------------------------
    GLEW Extension Info
---------------------------

GLEW version 1.4.0
Reporting capabilities of display :0.0, visual 0x2b
Running on a GeForce 8500 GT/PCI/SSE2 from NVIDIA Corporation
OpenGL version 2.1.1 NVIDIA 100.14.11 is supported
[snipped]

glewinfo further says I have almost all the GL_NV features.

Another indication that the drivers are ok is that I don't
see any problems with xscreensaver-gl provided screen-savers.

[Message part 1 (text/plain, inline)]

Hello,

Here's debdiff against rss-glx-0.8.1-11 with patchset to
  1. fix frame time calculations when frame limiter is enabled.
  2. allow --nice/--max-fps options to disable frame limiter.
  3. enable frame limiter and set default fps 50.

With 1. and 3. rss-glx screensavers doesn't hog 100% CPU anymore,
patch 2. is because --nice/--max-fps were there only to enable
frame limiter and couldn't be used to disable.

 - Jussi

Have you submitted this upstream? I'd rather get it accepted there.
