Hi. I built 1.4.3 with the following changes to Makefile.cfg: INCLUDE_G400_DRIVER = y INCLUDE_FBDEV_DRIVER = y INCLUDE_G400_DRIVER_TEST = y INCLUDE_NORMAL_DAC = y # Comment out any dac you don't want to autodetect. None, but I noticed they're built. Why ? ramdac/ramdac.o ramdac/normal.o ramdac/attdacs.o ramdac/sierra.o ramdac/icw.o ramdac/s3dacs.o ramdac/IBMRGB52x.o clockchip/icd2061a.o I thought my build would only include ramdac/ramdac.o ramdac/normal.o And what about clockchip/icd2061a.o ? And I'm not sure if I need INCLUDE_NORMAL_DAC = y So, this is a minimal SVGALib. I have a Matrox Millenium G400 (M4A32DG) and am using matroxfb with Kernel 2.4.5. From dmesg: Kernel command line: BOOT_IMAGE=1 root=301 video=matrox:vesa:440 matroxfb: Matrox unknown G400 (AGP) detected matroxfb: MTRR's turned on matroxfb: 1024x768x24bpp (virtual: 1024x5460) matroxfb: framebuffer at 0xE2000000, mapped to 0xd8805000, size 33554432 fb0: MATROX VGA frame buffer device I built seejpeg to test, but I get the following error: svgalib: Failed to initialize mouse. Cannot find a 256 colour video mode svgalib: mmap error rrr If I chmod +s seejpeg I don't get "svgalib: Failed to initialize mouse.". I only see "svgalib: mmap error rrr message" when I switch back from another vc. Until then it's a blank line. The only changes to /etc/vga/libvga.config: mdev /dev/tts/0 (I'm using devfs) chipset FBDev HorizSync 30.0 61.0 VertRefresh 50 120 OK, I solved the problem. The fbdev driver doesn't use the FRAMEBUFFER environment variable, and I don't have /dev/fb0. Here I use FRAMEBUFFER=/dev/fb/0. I don't enable compatibility for old device names in /etc/devfsd.conf. It seems to work, but I get the following in /var/log/messages: pervalidus kernel: matroxfb: cannot set xres to 400, rounded up to 416 pervalidus last message repeated 13 times pervalidus gpm[6564]: Skipping a data packet (?) I still have a question. Can I use chipset G400 with matroxfb, or I should boot without it ? -- 0@pervalidus.{net, {dyndns.}org} Tel: 55-21-717-2399 (Niterói-RJ BR) ------------------------------------------------------------------ Unsubscribe: To: listbot@svgalib.org Body: unsubscribe linux-svgalib
