-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello,
I've been talking with Felix Kühling about a problem I've been observing WRT DRI, my Radeon, and KDE 3.1, and he suggested that it might be time to submit a bug report to the devel list, so here I am. The summary of the problem is that, with accellerated GL enabled, I get a lag of 2 seconds each time the mouse pointer changed "modes." First, I'm using KDE 3.1, which provides a shaded, transluescent mouse pointer for the I-bar and the arrow; the other pointers (the hourglass, the hand, the resize shapes) are the regular X shapes. Also, I'm running on an ATI Radeon Mobility M7 (7500), on Gentoo, with the 2.4.20 kernel and the radeon driver from DRM. 1) The problem only occurs when DRI is enabled; specifically, the problem does not occur when running X under the fbdev, or when using the DRM Radeon driver with DRI and GL disabled. 2) The lag is caused by X consuming 100% of the CPU. The pattern is very uniform; the lag is always the same length, and is always (and only) caused by the same event. For that two seconds, X completely takes over the machine, and then releases it nicely. I see no error messages in any log files (dmesg, syslog, or XFree log). 3) The lag does not occur when switching between pointer shapes of the same "mode"; IE, switching between two fancy pointers, or between any of the standard pointers, causes no lag; it is only when switching from fancy to standard, or standard to fancy. 4) The option SWCursor fixes the problem, but then of course causes X to crash when trying to access any of the OpenGL functions. I'll be happy to provide any debugging information that may help fixating this problem. I can also list the message numbers of my conversation with Felix, if that'll help. Thanks. - -- ### SER Deutsch|Esperanto|Francaise|Linux|Java|Ruby|Aikido|Dirigibles ### ### http://www.germane-software.com/~ser jabber.com:ser ICQ:83578737 ### ### GPG: http://www.germane-software.com/~ser/Security/ser_public.gpg ### -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) iD8DBQE+T/usP0KxygnleI8RAiH/AKCLMOuvDZErMCxgYPQrcas9K20fOgCfTTUE VeCgWyeacZFV7/Fu8m3L86o= =sV5H -----END PGP SIGNATURE----- ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
