X11 On Hi-Resolution TFT Displays? 7
jesyntax asks: "Does anyone know how to get my 1280x1024 TFT working in Linux? When loading RedHat Linux 7.0 on my Gateway Solo 9300 laptop, I cannot seem to get it to go to graphics mode. The Linux installer does not detect the video hardware and when setting the 'settings' manually, the choices do not make sense for a laptop (TFT or LCD). I could not find a usable choice in the settings anywhere, but some TFT and LCD screens were listed in the options. These flat screens do not have a scan frequency per-se because they do not have to draw the lines on the screen as with a CRT monitor. Instead they have a fixed number of transistors which makes them not have lines but dots. There was no way in the manual settings to specify this."

the graphics card still scans across and changes the pixels
so yes when you spec it scan lines count
but the refresh rate also counts because LCD have a very limited amount i.e. how fast they can change

p.s. I have a SGI flatscreen and a #9 card you will see that they are supported in 4.02 and have the modline in there AND the multi link adapter
cheers SGI ! (BTW apples screen is the same but differant interface)

XFree86 Version 4.0.2 says:

....
According to the ibm-homepget this panel supports a dotclock of 108.0 MHz.
so I wrote a modline:
Mode "1400x1050"
DotClock 108.0
HTimings 1400 1450 1500 1600
VTimings 1050 1100 1150 1250
EndMode
I guessed the HTiming and VTimings, but they are working
ps.
DPMS is not Working
die kernel-fb (2.4.0) freezes the whole system.
if i kill X11 with Strg-Alt-Backspace the lcd get black and connot be activatet again.
the same happes on suspend or standby.
I'm not sure what the problem is... (Score:2)
XF4 seems to be VERY smart when presented with a decent chipset. My ATI Rage Pro IIc AGP lets me do this:
Works like a charm. This is a 1024x768 TFT screen but I don't see how it'd be any different on bigger (and nicer, you bastard) screens. :-)

that second link basically says, that he told the installer that he was using a 17" monitor capable of 1280x1024. I don't see why that wouldn't work.. you could probably tell it to use whatever sync rates it wants... I remember having to do something like that on my laptop when 1024x768 was new.

not exactly what you asked.... (Score:2)

Searching google suggest that people have some difficulties with the card on this laptop (not the screen per se) http://www.eecs.umich.edu/~steveh/inspiron/gw9300
Welcome to the world of making linux work on less than generic hardware. It's not as bad as that last snetence makes it sound actually, and is getting better all the time.
What you need to do is search ont he web and find people who have already done it and posted their results. And if you find anyhting new, post it yourself. I'd do it for mine, except for my laptop I can't better the work of Graham Williams! [csiro.au]
Try XFree86 4.02 (Score:3)
I used Xfree86 -configure to grab all those values and create a working XF86Config. It will grab your monitor's specs from the video card (yep, it worked on my TFT and my 19 inch CRT at home). If you're using SuSE, SaX2 is a frontend to this, and is quite cool, giving you a lot of control.
I'd suggest giving it a try, you'll probably get working modelines.
