[Ubuntu-x-swat] [Bug 301958] Re: [needs-packaging] no working driver for sis 671/771 video cards
Hi Antonio, I notice that you have links to compiled version of sis671 driver for Ubuntu 10.10 (Maverick) do you have the src code available? if not can you let me know which source code your working from so I can obtain a copy...Many Thanks. -- [needs-packaging] no working driver for sis 671/771 video cards https://bugs.launchpad.net/bugs/301958 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
[Ubuntu-x-swat] [Bug 301958] Re: [needs-packaging] no working driver for sis 671/771 video cards
Hi everyone, I have made some fudges to the src code (modifying BARCO_1366 special timings to suit my purpose) and managed to get 1360x768 (virtual size 1368 x 768) seems to work fine in kdm (with one exception...if I try to go into Display settings at which point the screen goes blank). Still some bugs to work out - around restoring screen resolution if I close laptop lid and open again etc. As soon as I have ironed them out, I will updated src with more eligant solution and post it!

[Ubuntu-x-swat] [Bug 301958] Re: [needs-packaging] no working driver for sis 671/771 video cards
Thanks stephan202! I have done some further digging and it appears to be related to the BIOS/EDID miss reporting informationMy screen is a 15.6 HD LCD 1366x768. the driver doesn't detect LCD correctlyso by default ends up with res of 0x0. :( I did false the screen 1024 x 768 by fudging some of the code in sis_vb.c file and re-compilingit didn't quite sort out the problem...it appeared to load the screen X (gdm logon) but as soon as X tried to refresh the screen (ie if I logged in via gdm or if I switched to a Text screen (using crtl+alt+f1 and then back to X screen) - screen goes black then fade to white from all four edges of the screen - like the frequencies where way out. ) :/ So I decided that I need to start reviewing understanding the source code before I continuingor find someone how is familiar with the code to look at the problem further. -- [needs-packaging] no working driver for sis 671/771 video cards https://bugs.launchpad.net/bugs/301958 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
[Ubuntu-x-swat] [Bug 301958] Re: [needs-packaging] no working driver for sis 671/771 video cards
ok, I went back to source code and had a quick look. since the screen is set wrong, i placed a fudge in the code to test. since I didn't want to take chances the fudge was for 1024x768. Xorg.0.log now has (--) SIS(0): Detected LCD/Plasma panel (max. X 1024 Y 768, pref. 1024x768, RGB24) xorg goes on to detect the resolution but still doesn't display an screen. If I switch on the xorg.conf Option VESA yes I get an Xsession.So, clearly something else is going on here - Can someone who as a LAPTOP with SiS671 graphics card Widescreen LCD that works - post a copy of there Xorg.0.log so I can compare there output to mine. It may provide further clues as to what I need to change.

[Ubuntu-x-swat] [Bug 301958] Re: [needs-packaging] no working driver for sis 671/771 video cards
I have same problem as koan. I am using ubuntu 9.10 64-bit. SiS driver doesn't detect SIS672 chip so I downloaded SIS671/672 Driver from http://ncc-1701a.homelinux.net/~linux- sis/index.php?page=Downloads I have an ASUS X5DC laptop. It appears that the reason the modes are detected is that the laptop screen fails to supply EDID information. this results in LCD being detected but with max screen size of 0x0 with pref 0x0 see xorg entry below: (--) SIS(0): Detected LCD/Plasma panel (max. X 0 Y 0, pref. 0x0, RGB24) Xorg then fails to detect any workable screen resmode pool is empty. I have tried to set HSync/VRefresh and add Modelines but had no luck. In Windows 7 the LCD Screen is set as a Generic Monitor...EDID Information is in Registry, it appears that the manufacturer is able to override/fake EDID information for non-compliant/corrupt EDIDs. If I plug-in an external EDID Compliant Monitor the Driver works on the external screen but LCD is blank. Is there away to fake/ignore EDID information like the NVIDIA Driver? -- [needs-packaging] no working driver for sis 671/771 video cards https://bugs.launchpad.net/bugs/301958 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

Hi Antonio, To confirmI have tried the driver on the link you provided...(in fact that was the driver I was trying!) but thanks! The driver detects the Video Adapter but the integrated LCD panel still doesn't work. when I try to run X screen flashes several times and ends up with Mode Pool Empty. The LCD still detected but says max res 0x0 pref 0x0. Xorg.log reports: (EE) Screen(s) found, but none have a usable configuration. I believe that is due to lack of EDID information for the integrated LCD Screen. Modelines /Modes and HorizSync/VertRefresh lines dont appear to override it. here is the output from I from get-edid: get-edid: get-edid version 2.0.0 Performing real mode VBE call Interrupt 0x10 ax=0x4f00 bx=0x0 cx=0x0 Function supported Call successful VBE version 300 VBE string at 0xc2d66 SiS VBE/DDC service about to be called Report DDC capabilities Performing real mode VBE call Interrupt 0x10 ax=0x4f15 bx=0x0 cx=0x0 Function supported Call successful Monitor and video card combination does not support DDC1 transfers Monitor and video card combination does not support DDC2 transfers 0 seconds per 128 byte EDID block transfer Screen is not blanked during DDC transfer Reading next EDID block VBE/DDC service about to be called Read EDID Performing real mode VBE call Interrupt 0x10 ax=0x4f15 bx=0x1 cx=0x0 Function supported Call failed The EDID data should not be trusted as the VBE call failed Error: output block unchanged As I said in my last post if I connect a monitor to VGA port and configure X to use it - the EDID is detected and screen is configured correctly.

[Ubuntu-x-swat] [Bug 301958] Re: [needs-packaging] no working driver for sis 671/771 video cards
Dirk, Thanks but I have tried that. I have also tried other options i.e. UseEdidFreqs false IgnoreEDID true NoDDC true none of which workI assume they are driver dependent, since they appear to be be used differently between drivers. for example radeon uses NoDDC nvidia uses UseEDID I also tried Option useROMData False suggested in one of the posts on this bug thread. but no joy. -- [needs-packaging] no working driver for sis 671/771 video cards https://bugs.launchpad.net/bugs/301958 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

Its a shame that the nvidia option for custom edid (Option CustomEDID DFP-1:/etc/X11/edid.bin) isnt available for SiS67x driver because I can extract EDID from Windows 7 Registry. -- [needs-packaging] no working driver for sis 671/771 video cards https://bugs.launchpad.net/bugs/301958 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
