What kind of information is (not!) in the BIOS that tells X how to change the resolution? A function? A memory address? Something else? Changing the resolution on a video card requires writing a number of timing and configuration registers directly to the chip hardware. The definitions, usage, interactions, and philosophy of those registers are often quite complicated, and vary wildly from manufacturer to manufacturer. The video BIOS knows how to write those registers when you make a VBE INT 10 call, because the engineers that designed the chip wrote that BIOS. The Windows driver knows how to write those registers, because a team at the chip manufacturer wrote that driver with the assistance of the design engineers. However, chip manufacturers often do not write XFree86 drivers, because it represents approximately 0% of their annual sales. Further, more and more chip manufacturers consider their chip specs to be proprietary, so they are not released without a license agreement and a set of stiff legal handcuffs. Without the chip specs, the only way a non-Windows driver can set the video mode is by asking the BIOS pretty please. If the BIOS has been crippled by not supporting certain modes, then X will be crippled in the same way. I was astounded to learn that many laptops with Intel graphics chips ship with 1400x1050 LCD panels, and a video BIOS that does not support 1400x1050 mode. That's just criminally negligent. There is nothing we can do, short of reverse engineering, which has its own set of legal issues. I am asking this because, if I have more information about what is possibly broken/missing in the BIOS, I can try to contact the manufacturer and ask for a fix. Without specific information it is difficult to get a useful answer from the manufacturer (COMPAL). You will find no help at COMPAL. All they do is repackage the BIOS and drivers from Intel. It is quite likely they don't even have a graphics driver writer on staff. -- - Tim Roberts, [EMAIL PROTECTED] Providenza Boekelheide, Inc. ___ Devel mailing list Devel@XFree86.Org http://XFree86.Org/mailman/listinfo/devel

Re: External CRT works on 1024x768 but LCD not. Please Help!!!
Actually, From the look of your log file, the 1024x768 mode isn't supported at all on your LCD. And although your LCD is reported at 1024x768 it looks like your BIOS is broken. ModeAttributes should show 0x9b, whereas it's showing 0x9a. That first bit is dictating whether XFree86 allows the mode or not, as it's VBE's method of saying if the mode is supported in the current configuration. Have you double checked for an updated BIOS ?

Re: External CRT works on 1024x768 but LCD not. Please Help!!!
Hi, Thanks for your attention. Regarding the BIOS, I am using the latest version available. Sorry to ask that but, if the BIOS is broken, why, under WindowsXp, the LCD works in 1024x768? Why, with X11, the CRT works in 1024x768? Should not the broken BIOS prevent the LCD from working under WindowsXP and the CRT under X11? I am not sure if I understood correctly the role of the BIOS in the proccess. Also, can´t I override this ModeAttribute? Can´t I set it to 0x9b? Would this fix the problem? Thanks again.

The graphics chipset is (as reported by lspci): :00:02.0 VGA compatible controller: Intel Corp. 82852/855GM Integrated Graphics Device (rev 02) :00:02.1 Display controller: Intel Corp. 82852/855GM Integrated Graphics Device (rev 02) The 82852GM supports two independent display.

I read all material on the net about the memory/vbios problems with this chipset. I do not think I have this problem because I can change the memory allocated to the graphics card in the BIOS setup program, and the XFree output reflects these changes. I have tried all kinds of patchs, all the latest XFree versions available (including 4.4.0), several distros (FC1, FC2, Mandrake 10 and now, Debian unstable), the IBM driver, asked the dealer and manufacturer for a BIOS update, but my LCD never reaches 1024x768 (only 800x600 and 640x480). Actually, a few months ago, I gave out trying to make the LCD work under 1024x768, after all this dozens of failed trials. I am getting back to this because I just find out that, if I connect a external CRT monitor (actually a Samsung SyncMaster 700p) to the CRT out of my laptop, 1024x768 works on it! I am completely puzzled. I suspect the reason it works is that your system have two graphics controller. And one of it is the 350Mhz 24-bit RAMDAC that support a regular scan analog monitor. If XFree can make the external monitor works on 1024x768, why it can not do the same with the LCD? LCD and CRT don't use same code. I was told that my graphics chipset has a vbios problem that prevents Xfree from recognizing its ability to work under 1024x768, but, if this is true, why that external CRT works under 1024x768? I must note that under WinXP the LCD works on 1024x768 and that the XiG X server can also do the same. Now that it is clear that Xfree can produce 1024x768 with my chipset and my LCD supports 1024x768, how can I force Xfree to try 1024x768 on the LCD? My XF86Config-4 can be found here: http://paginas.terra.com.br/educacao/nqnsome/xf86config.txt The XFree output can be found here: http://paginas.terra.com.br/educacao/nqnsome/xfree_output.txt I am really sorry for my bad English.

That is what Alex meant when he said you have two device on one component. Thanks a lot. Regards, Sergio -- No virus found in this outgoing message. Checked by AVG Anti-Virus.

Hi, Thanks again. Alex Deucher wrote: Alex is correct. Let focus on the primary display controller on PCI:0:2:0 with Display Pipe A and Display Pipe B. In your case you can only have PipeA=CRT and PipeB=LCD (LFP). That is why you have the following information (II) I810(0): Display Info: CRT: attached: TRUE, present: TRUE, size: (800,600) (II) I810(0): Display Info: LFP (local flat panel): attached: TRUE, present: TRUE, size: (1024,768) The problem is why XFree is saying there is no active display on Pipe B (II) I810(0): No active displays on Pipe B you can use the monitorlayout option to force on the pipes. see the i810 man page. Alex Now I understand the Pipes, but is still a mistery for me why lspci sees the 0:2:1, if it is a Windows placeholder (propably because I do not understand what a placeholder is...). Regarding the No active displays on Pipe B, this probably happens because, before starting X, I disable the LCD with the keyboard sequence FN+F5. If I do not do this, the screen becomes unreadble (I guess because the CRT works in 1024x768 and the LCD do not). Thanks a lot for the explanations, but I would like to return to the question why the CRT works under 1024x768 and the LCD not. Can this be related to the VESA VBE DCC that does not work on the LCD?

If I do not do this, the screen becomes unreadble (I guess because the CRT works in 1024x768 and the LCD do not). that's the problem. the i810 driver relies on the bios to deal with outputs and modes. if tyou use the bios to disable an ouput, the driver probably has problems detecting an attached device.

Re: External CRT works on 1024x768 but LCD not. Please Help!!!
Hi, Thanks for answering. 1)Booting only on the LCD does not work. The XFree output is here: http://paginas.terra.com.br/educacao/nqnsome/xfree_output_lcd_only.txt Note that X11 does not find anymore the Built-in mode 1024x768, that it finds when the CRT is attached and I turn off the LCD before starting X11. Why turning the LCD on prevents X11 from finding the Built-in mode 1024x768? Isn´t the mode Built-in? 2)If I boot with both devices attached to the notebook and turned on, 1024x768 does not work in any of them. The output is here: http://paginas.terra.com.br/educacao/nqnsome/xfree_output_both.txt 3)If I boot with both devices attached to notebook, but with the LCD off, X11 finds the Built-in mode 1024x768 and the CRT starts in 1024x768. If I try to turn the LCD on, the screen gets messed up, and I have to restart X in order to see something. When I restart, both the CRT and LCD turn to 800x600. I was told months ago that the Built-in modes are read from the VBIOS, but this does not seem to be the whole true, since the attached display device interferes in the detection. BTW, the LCD works in 1024x768 in WinXP.

External CRT works on 1024x768 but LCD not. Please Help!!!
Hi, Can someone help me, please!? I have a Compal CY27 laptop. The graphics chipset is (as reported by lspci): :00:02.0 VGA compatible controller: Intel Corp. 82852/855GM Integrated Graphics Device (rev 02) :00:02.1 Display controller: Intel Corp. 82852/855GM Integrated Graphics Device (rev 02) I read all material on the net about the memory/vbios problems with this chipset. I do not think I have this problem because I can change the memory allocated to the graphics card in the BIOS setup program, and the XFree output reflects these changes. I have tried all kinds of patchs, all the latest XFree versions available (including 4.4.0), several distros (FC1, FC2, Mandrake 10 and now, Debian unstable), the IBM driver, asked the dealer and manufacturer for a BIOS update, but my LCD never reaches 1024x768 (only 800x600 and 640x480). Actually, a few months ago, I gave out trying to make the LCD work under 1024x768, after all this dozens of failed trials. I am getting back to this because I just find out that, if I connect a external CRT monitor (actually a Samsung SyncMaster 700p) to the CRT out of my laptop, 1024x768 works on it! I am completely puzzled. If XFree can make the external monitor works on 1024x768, why it can not do the same with the LCD? I was told that my graphics chipset has a vbios problem that prevents Xfree from recognizing its ability to work under 1024x768, but, if this is true, why that external CRT works under 1024x768? I must note that under WinXP the LCD works on 1024x768 and that the XiG X server can also do the same. Now that it is clear that Xfree can produce 1024x768 with my chipset and my LCD supports 1024x768, how can I force Xfree to try 1024x768 on the LCD? My XF86Config-4 can be found here: http://paginas.terra.com.br/educacao/nqnsome/xf86config.txt The XFree output can be found here: http://paginas.terra.com.br/educacao/nqnsome/xfree_output.txt I am really sorry for my bad English.

I can't look into this problem tonight I will be able to see if I can help you tomorrow. If you need to use your laptop without the external crt, use the vesa driver for now.
