Actually Thomas Winischhofer explains this problem here http://www.winischhofer.eu/linuxsispart1.shtml#21
First politic "Pretty simple: SiS is unfortunately one of those companies that do not support Linux or X.org/XFree86. They don't (and will not) release any documentation on their products (with a few exceptions) and write drivers only for Microsoft's DOS-extensions (called "Windows" by many people; and yes, "Windows" is a trademark). Although they have released XFree86 drivers previously and have released a (binary) driver for the SiS650 in the past, these are and were heavily buggy and not developed any further from a certain point. In other words: Their XFree86 drivers are useless. If you have a notebook, you don't even need to consider trying them." Then technics and comparison to windaube "My advice: Don't buy a machine with a SiS760 unless this machine has dedicated local video memory. And please don't complain about "driver bugs" if you see "flashing lines" on the screen; these are the typical effects of a bandwidth problem and unavoidable - even the Windows driver can't do better. In such cases, reduce the resolution and/or refresh rate and/or color depth, or use one output (CRT1 or CRT2) only. Sorry, can't help it. There is no driver bug involved. For poor Averatec 6240 users: My drivers at least allow 1280x800 on the LCD if the external monitor is enabled... the Windows driver kicks you back to 1024x768 in such a case." In conclusion down the depth, the resolution or the refresh rate. -- Screen Refresh issues with SiS 760 https://bugs.launchpad.net/bugs/65573 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
