I want to be able to use an external monitor with an Asus M3N laptop with i855 chipset and integrated 64MB Intel graphics. The laptop has a SXGA+ 1400x1050 lcd, but so I still cannot use that resolution. I have still been unable to get an acceptable display on an external monitor, and I hope someone here can help. Here is what I have tried so far. 1) The FnF8 key is supposed to toggle between lcd, lcd+crt, crt. For me it switches between lcd-only and crt-only but is never usable (even switching back: lcd->crt->lcd). In the best case the desktop is displayed below a band of noise at the top of the screen and with its bottom cut off. Other times the whole display is a mess. Switching to another vt and back will restore the display to good condition on the lcd. 2) There is a tool called i810switch which writes to a location in /dev/mem. This successfully activates the external crt when it is attached. Unfortunately the display is out of focus and some monitors report the signal as out of range. The tool can turn off the monitor too, but cannot activate the lcd on an i855. 3) The asus_acpi project provides a kernel module and /proc interface. Reading from /proc/asus/acpi/disp should give a number related the current display state, and writing to the file should change the state. Remarkably, a simple read of the file will distort the lcd by putting the band of noise at the top of the display. Nothing I write to the file has any affect. 4) I thought I might configure XF86 to drive the external display in the config file, but the few things I tried failed. Any ideas how to get this to work? If #4 has a chance and you want to see my config, just ask. BTW, of course I suffer from the unavailability of 1400x1050 in the BIOS, so I am using 1280x1024 for now. I really would like to solve that problem too. Thank you very much, -- L _______________________________________________ XFree86 mailing list XFree86@xxxxxxxxxxx http://XFree86.Org/mailman/listinfo/xfree86
