Hello People, I got a Matrox Millennium G200 AGP (rev. 1), with 8 MB RAM. I use a resolution of 1024x768 in 16bpp.
Since I upgraded to XFree86 4.2.1 from 4.1.0 (which happened recently in Debian sid), I cannot use Xv anymore for big sources. An example: When playing back a media file using "mplayer -vo xv" which is 320x240 pixels in size, I can correctly view it and use Xv to scale it to any size (up to full screen, 1024x768). But when playing back a DVD (in 720x576), it doesn't work: I immediately get the following error, when mplayer tries to open the window: X11 error: BadAlloc (insufficient resources for operation) Also by using xawtv to display a v4l input signal (using Xv for colorspace transform), it works fine up to a certain size, after which I get the same error: X Error of failed request: BadAlloc (insufficient resources for operation) Major opcode of failed request: 142 (XVideo) Minor opcode of failed request: 19 () The "critical size" seems to be around 420000 pixels (i.e. for example a source of 1000x410 pixels can be scaled using Xv, while 1000x420 can't). This applies to a "normal" run of X, including the "dri" modules. When starting X without "dri", either by starting two X servers at once (so the second one can't do dri), or by commenting out the 'Load "dri"' statement in XF86Config-4, then I can use Xv for all sizes (at least until 1024x768). Downgrading the mga_drv.o module to the 4.1.0 version "fixes" the problem. But both the 4.2.1 version from debian, as the 4.2.0 version from ftp.xfree86.org exhibit the behaviour i described above. Now, the whole problem looks like a shortage of memory to me. But, in my limited knowledge, I think that 8 MB should be enogh to do both DRI and Xv up to 1024x768 in 16bpp. So, I'm now asking the list: Is this a genuine bug in 4.2, which can be fixed - or is it just that I don't have enough video memory for "big" Xv anymore? If yes, can I configure XFree86 to use "less memory", as it did in 4.1? Or would I then miss serious functionality? Thanks for any pointers! -- Andreas Trottmann <[EMAIL PROTECTED]> _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
