Public bug reported: Binary package hint: xserver-xorg-video-sis
Since there are several reports on these bugs in xserver-xorg-driver-sis I give a summary of the reported problems and some of the suggested solutions. SIS does not provide all required information to make good drivers for all SIS graphical cards. Hence you might meet problems with some monitors (resolutions, modes) and you will not get 3D acceleration. bug 1: The driver sis available in Ubuntu (Karmic) does not function well for all SIS graphical cards (e.g. see bugs 523749, 301958, 281454, 291294, etc and various questions) Minor bug 2: In "man sis" the link http://www.winischhofer.AT/linuxsisvga.shtml should be replaced by http://www.winischhofer.net/linuxsisvga.shtml Discussions on internet, especially Ubuntuforums show that many, sometimes conflicting, advices are given which seem to work for only part of the users. The following advices are given: - Check http://www.winischhofer.net/linuxsispart1.shtml#12 for supported SiS/XGI graphics chips and video bridges. - Also check what input is used by the monitor. If you have a choice between analog and digital input you may have to use analog (see tables on the same link which show that for higher resolutions only analog works). For that you use a VGA plug (15 pin D-sub). It is found on most (if not all) machines including laptops for primary VGA output, thus driven by CRT1. If it is not present you may need a DVI-VGA adapter or to remove some pins. - It may be necessary to configure /etc/X11/xorg.conf. If you do not have this file you can generate one with Xorg -configure while gdm is not active. Do this before installing new drivers and check for modifications after installing new drivers. Especially the choice of the driver in the Section Device may be important. E.g.: Section "Device" Identifier "devname" # your device Driver "sis" # or sisimedia or sis671 - It may be necessary to reduce Shared Memory in the BIOS (see bug 291294 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- sis/+bug/291294) - If needed, download the drivers sisimedia and/or sis671 from http://ncc-1701a.homelinux.net/~linux-sis/index.php?page=Downloads (Available in Lucid?) - When you switch monitors it may be needed to completely remove (purge) one of the sis-drivers and reinstall it and/or to reconfigure xorg.conf and/or the BIOS (e.g. see bug 523749). - The sisfb module is mentioned also. E.g.(Bug #264769): sudo modprobe sisfb AND edit your xorg.conf at: Section "Device" add there an: Option "UseFBDev" "true" Another example: add "video=sisfb" as kernel argument on menu.list and later grub.cfg (Bug #530554). Another example: add sisfb in /etc/modules My tip: Before you take any actions read "man sis", visit http://www.winischhofer.net/linuxsispart1.shtml#12 and https://help.ubuntu.com/community/Video, and search ubuntuforums and launchpad with "sis graphics" and the name of your version of Ubuntu to check your method. Remember that tips may not be valid in your case because the hardware and software configuration of your pc may not be equal to that of the tipper. ** Affects: xserver-xorg-video-sis (Ubuntu) Importance: Undecided Status: New -- Summary of sis graphics bugreports https://bugs.launchpad.net/bugs/549645 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-sis in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
