** Summary changed: - totem overrides XV_CONSTRAST to wrong default value (Xv movies on i810/i945 have horrible colour/gamma) + totem overrides XV_CONSTRAST/XV_SATURATION to wrong default value (Xv movies on i810/i945 have horrible colour/gamma/contrast)
** Description changed: - I bought a new desktop with a Foxconn 945G7MA-8EKRS2 motherboard [1]. + Totem (in some Ubuntu versions only -gstreamer or -xine variants) + overrides XV_CONTRAST/XV_SATURATION to wrong values, this causes viewing + movies with accelerated XV Intel and I810 drivers (i855/i810/i945/etc + video cards) have horrible (distorted) colors/gamma/contrast/brightness + (in such case it's pretty hard to set correct color balance in totem's + preferences, often you need to change not only contrast, but also + saturation from standard values). - I installed Dapper Flight 4 and bug 27180 occurred. I chose i810 and - results in a working X. However, whenever I play video, the colors are - distorted very much. + Most other media players (vlc, mplayer, gxine, etc) doesn't have this + problem, AFAIK. Also this problem disappears by changing video output + driver from XV to X11. Note: XV_CONTRAST/XV_SATURATION should be reseted + to real defaults before running another media player, as in most cases + totem changes XV_CONTRAST/XV_SATURATION for whole session, until you + reboot. - I tried with mplayer and found that if I switch the video driver from - "xv" to "gl", then colors will be ok, but very slow. Of course, totem - won't let me switch the driver either --- Where has "Multimedia System - Selector" gone? + In some Ubuntu versions (for example in Ubuntu 7.10 "Gutsy") this + problem appears only with totem-xine, in other (e.g. 8.04 "Hardy") - + only with totem-gstreamer, AFAIK problem is in both totem variants in + older Ubuntu versions (e.g. 6.06 "Dapper"). - I cannot test using Breezy since it hangs somewhere during booting the - Live CD. + Example of testcase (applies to Ubuntu 8.10 Hardy's driver, as well as + Debian experimental, date 2008-04): - [EMAIL PROTECTED]:~$ sudo lspci -v - ... - 0000:00:02.0 VGA compatible controller: Intel Corporation 945G Integrated Graphics Controller (rev 02) (prog-if 00 [VGA]) - Subsystem: Foxconn International, Inc.: Unknown device 0cc0 - Flags: bus master, fast devsel, latency 0, IRQ 193 - Memory at fdf00000 (32-bit, non-prefetchable) [size=512K] - I/O ports at ff00 [size=8] - Memory at d0000000 (32-bit, prefetchable) [size=256M] - Memory at fdf80000 (32-bit, non-prefetchable) [size=256K] - Capabilities: [90] Message Signalled Interrupts: 64bit- Queue=0/0 Enable- - Capabilities: [d0] Power Management version 2 - ... + System: + Dell Inspiron 510m, 00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02) + xserver-xorg-video-intel package version 2:2.2.1-1ubuntu12 - My monitor is LG L1950S. + Test case: + 1.

Open a movie using a different movie player (totem-xine, totem-gstreamer, vlc, mplayer, gxine, etc), close it, then get a new reading via xvattr; e.g. after playing a movie in VLC: "xvattr >xvattr.vlc" (or during the play) + 4. Compare files, e.g.: diff -u xvattr.default xvattr.vlc + 5a. If there is a difference, you will need to reset xvattr to "default" settings before trying another movie player (this can be done by rebooting computer). + 5b. If there is no difference, repeat step 3 & 4 with a different movie player. + Expected results: + No movie players change XV settings - [1] http://www.foxconnchannel.com/products_motherboard_2.cfm?pName=945G7MA-8EKRS2 + Actual results: + Totem (only using the gstreamer backend) and SMplayer (this can be another bug) causes XV settings to change each time a movie is opened.
