Hi, I've been quite frustrated for a whole week. I'm using Xfree86 4.2 with Slackware 8.0 on my IBM Thinkpad a20p with 1400x1050 LCD panel and Rage Mobility M-3. The detection of the screen is quite ok, I even do not need to add modeline for 1400x1050 that it works automatically. But the problem is, I cannot get any resolution below 1024x768, which I think is quite important for running SDL applications. An interesting thing is that, the xfree86 version in Mandrake 8.1 can detects 640x480 up to 1400x1050, but either slackware's or xfree86's original binary can not. I've tried copy Modelines using xvidtune from mandrake to slackware, but it does not help. Also not helping is copy XFree86Config-4 from mandrake to slackware. Anyone can help me? Forgive my poor english, it's not my native language. PS: Lines i think may help in XFree86.0.log (II) R128(0): VESA BIOS detected (II) R128(0): VESA VBE Version 2.0 (II) R128(0): VESA VBE Total Mem: 16384 kB (II) R128(0): VESA VBE OEM: ATI MOBILE M3 (II) R128(0): VESA VBE OEM Software Rev: 1.0 (II) R128(0): VESA VBE OEM Vendor: ATI Technologies Inc.
