Re: Need Help getting 1280X1024 on Dell Inspirion 7500
- The modeline you mentioned is in fact inside my XF86Config file.
After X started, I searched /var/log/XFree86.0.log & came up with the
following references to "1280"
(--) ATI(0) virtual size is 1280x1024 (pitch 1280)
(**) ATI(0) Mode "1280x1024": 107.9 MHz, 59.1 KHz, 54.8 Hz
(II) ATI(): Modeline "1280x1024" 107.97 1280 1312 1432 1704 1024 1026
1029 1054 (null)
Also, for what it is worth, I set the VertRefresh to 50.0-100 as
directed by http://support.jp.dell.com/docs/systems/psyd/overview.htm
but this didn't seem to change anything as things still do not look
Furthermore I should clarify what I mean by things do not look
right. In 1400x1050, I see a solid gray background after I login &
start X/mwm. In 1280x1024, there are light & dark gray vertical
strips, maybe 10 pixels wide. On top of that, occasionally
individual words within an xterm seem to be fuzzy. That is maybe the
top pixel of a words will be duplicated one pixel higher or vice
versa for the lower pixel.
Can some e-mail me an XF86Config file where they are successfully
running Linux 7.2 using XFree 4.1 where the screen is 1280x1024?
Thanks in advance
