| |
Upon bootup, radeonfb is obviously not initializing the hardware correctly. Massive amounts of random-looking garbage, plus a weird effect I've never seen before, like someone pouring milk _up_ the screen. (Yeah, it's the best I could come up with)
It's a Dell Inspiron 8600 with Mobile Radeon 9600 and 1920x1200 LCD.
Here's the relevant parts from dmesg:
radeonfb_pci_register BEGIN radeonfb: probed SDR SGRAM 131072k videoram radeonfb: mapped 16384k videoram radeonfb: Found Intel x86 BIOS ROM Image radeonfb: Retreived PLL infos from BIOS radeonfb: Reference=27.00 MHz (RefDiv=6) Memory=337.00 Mhz, System=243.00 MHz 1 chips in connector info - chip 1 has 2 connectors * connector 0 of type 2 (CRT) : 2300 * connector 1 of type 4 (DVI-D) : 4210 Starting monitor auto detection... radeonfb: I2C (port 1) ... not found radeonfb: I2C (port 2) ... not found radeonfb: I2C (port 3) ... not found radeonfb: I2C (port 4) ... not found radeonfb: Reversed DACs detected radeonfb: Reversed TMDS detected radeonfb: I2C (port 2) ... not found radeonfb: I2C (port 4) ... not found Non-DDC laptop panel detected radeonfb: I2C (port 3) ... not found radeonfb: I2C (port 4) ... not found radeonfb: Monitor 1 type LCD found radeonfb: Monitor 2 type no found radeonfb: panel ID string: radeonfb: detected LVDS panel size from BIOS: 0x0 BIOS provided panel power delay: 0 Scanning BIOS table ...

Obviously, it isn't detecting the screen size properly. I even tried hard-coding the resolution in the detection code, to no avail. Any suggestions?
Thanks.
