Actually it starts, but the display is corrupt: the last part of the screen lines are shown on top: 6 7 1 2 3 4 5 that means that 2/7th of the lines are shown on top, then I have a blank line, then I have the first 5/7th of the screen. And, this is not working in 1024x768 but 800x600. Please note that every X version I have is perfectly working sith an external monitor. The problems appears only using the LCD screen.

[Xpert]SiS630 and LCD status
Hi! I have a SIS630 based notebook running FreeBSD 4.4-STABLE. I checked out the latest cvs source and when starting the server I get a blank screen (I need to reboot the box to get output on the LCD again). The 1024x768 output on the VGA-Out works fine for me. I applied the patch from http://www.xfree86.org/pipermail/xpert/2001-July/009974.html to get it working - no signal on the vga out and a broken output on the LCD. The image is split into four parts. the lower left part is in the upper right corner. The upper left part in the lower right. This is how it looks: |---| | lower | | lower | | right| | left | |---| |---| | black | | | |---| |---| | upper | | upper | | right | | left | |---| The whole screen seems to be 640x480.

Your patch is pretty similar to the VESAFbHack patch posted a while ago. The VesaFBHack patch, which was my little effort at re-implementing the patch posted to this list by Kirill Konyagin (back in July 2001), may have been based on the same work as Rene, or Rene's work was based upon it. I simply put it into a form that allowed the user to easily enable/disable it. It also meant that if it was fixed, a config file change was not really necessary (something I was looking at, as I was investigating rolling these out into a production environment, and the less changes in the future, the better). Right. Your patch was OK. I'm thinking about adding it for 4.2. I doubt that I will be able to implement the BIOS initialization stuff. For the SiS to fully work with int10 I may have to modify some stuff in there code. I won't do that before 4.2 comes out. I'm thinking of something different: sis_bios.c is converted BIOS code anyway. Since we have the int10 infrastructure we can use it to run the real BIOS and eliminate much of the code in sis_bios.c. You might find that a lot of the code in the XFree driver is now the same as that in the Linux Kernel FrameBuffer for the SiS630 chip, so some common development here could be a definite advantage. I suggested this a long time ago. The problem was that kernel code was under GPL while ours was under an MIT style license. Something I have noticed as a difference between the VesaFB and SiSFB drivers in the Linux kernel, is that the VesaFB driver does it's init as absolutely early as it can, as the routines to change resolution have to be performed (afaik) in real mode, not in protected or virtual modes. AFAIK there is a way now to change VESA video modes on the fly. I tryed to get docu from sis - even considering signing a NDA - but suddenly the email thread with them stopped ... ? - They so not seem to be interested in getting the chip to work properly under Linux ... :-( I would certainly love to have better docs for the graphics part of the 630 than there are in the 630 datasheet. I got very little response from SiS, to very similar or the same queries (re: docs, NDA, sample code, etc). The company I work for wants to use a machine made by Clevo (a Taiwanese company) as a Point of Sale terminal (it's a desktop with an LCD screen, and very small footprint), but with the current problems we have with the SiS630 chipset (if not resolved soon), we will simply have to turn down the product as another good idea, bad implementation. Pity really, as the cost was reasonable, and the options on the product were ideal for our market. The problems can be resolved very quickly by using the video BIOS. The problem is we are past feature freeze for the 4.2 and I don't want to make modification to int10 code at this late stage. Int10 is quite touchy. If I get something wrong I'll have to take the blame. Egbert. ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert

Braunstein Alfredo writes: Did you have the same setup on the old version? How much video memory do you have? Could you please send the entire log file? If you have a log file from the old version (were 3D worked) could you please send this one, too? Regards, Egbert. Hi there. Here I attach full logs of 2 running sessions. 'log.cvs' and 'log.vesafbhack'. The setup is exactly the same for the two of them except for sis_drv.o and booting with or without the vesa fb, respectively. First case is sis_drv.o from latest CVS. The other one is that one using the VESA fb hack. I'm using Xfree CVS from 3-4 weeks ago. Note that I've only updated Egbert changes on the sis/ directory and nothing else; I am on a slow link at home. If you consider that it's definitely worth trying, I am willing to do a full CVS update. On the first case, (vesa framebufer), 3D accel seems to work. I say seems because Mesa demos work. I think Hw accel is being used because the gears in 'gears' have some glitches, like bad poligon superpositions, which I would find strange in a software-only renderer, But I may be wrong. How can I check for sure that Hw acceleration is being used? On the other case I get a 'not enough video mem' error, like I've said in a previous mail, when I run any Mesa demo. I've tried changing the video memory to 8Mb, 16Mb and 32Mb with no success. I'm currently using 8Mb for both tests (as you can see from the logs). Other differences: On the first case I get a strange xterm cursor, like: # # # # # # # # instead of a rectangle. On the second case it is gone (ok). Also I've observed a corrupted first line of the screen, but after a full reinstall It seems to have gone for both cases. This is the (I think) relevant differences between both logs: 16c16 (==) Log file: /var/log/XFree86.0.log, Time: Fri Dec 7 13:31:58 2001 --- (==) Log file: /var/log/XFree86.0.log, Time: Fri Dec 7 13:34:48 2001 82c82 compiled for 4.1.0, module version = 0.6.0 --- compiled for 4.1.99.1, module version = 0.6.0 208a212 (II) SIS(0): Mode # 0x4a 211,212c215,216 (II) SIS(0): [drm] added 4096 byte SAREA at 0xd08c8000 (II) SIS(0): [drm] mapped SAREA 0xd08c8000 to 0x40028000 --- (II) SIS(0): [drm] added 8192 byte SAREA at 0xd00c7000 (II) SIS(0): [drm] mapped SAREA 0xd00c7000 to 0x40028000 247,248d250 cursor_addr value: 0 cursor_addr value: 23 250c252 (II) SIS(0): [drm] unmapping 4096 bytes of SAREA 0xd08c8000 at 0x40028000 --- (II) SIS(0): [drm] unmapping 8192 bytes of SAREA 0xd00c7000 at 0x40028000 I hope that this reports can help you!

Egbert Eich: Rune Petersen writes: sorry had a lot on my mind... Doesn't work means: all except the topmost cm. is flickering between showing about 1/4 of the actual image (also looks streched vertically) and showing black. I' have tried without Framebuffer and got the same result. Hm, doesn't sound too good. The problem about the sis driver is: We have no decend documentation for the SiS 630. Even if we did we'd have a hard time: the code that sets up the chip was provided by SiS. What they did was very simple: they translated their i86 machine language BIOS code to C. The code looks horrible! It retreives register values from tables in the BIOS and writes them to the chip. It is very likely that later versions of the BIOS do some things the BIOS that served as base for this code didn't do. What happened when you used the old driver - without my patches? Regards, Egbert. The old drivers made the screen all white, to get it to work I had to patch the drivers so they didn't setup the LCD, an then use the VESA framebuffer to setup the display. I have no experience in this but the VESA framebuffer (as far as I know) uses the BIOS to setup the LCD and that works for me, any chance the same can be done with these drivers? or have I gotten it all wrong?
