XFree86 4.2.0 at 1024x600?
 

So I have this cool new laptop, the JVC MP-XP7210, and its internal monitor supports an ideal resolution of 1024x600. Its obviously not in the default resolutions so I attempt to add my own modeline:

modeline "1024x600" 51 1024 1032 1176 1341 600 600 606 626

to the monitor section of the "/etc/X11/XF86Config-4" file. I've also experimented with other monitor and screen settings. But to no avail. The closest to success I have gotten is (this is hard to explain) where the vertical settings are correct, but the horizontal settings make the screen stretch across LCD panel, distorting everything left-to-right. To see the entire screen I have to use the mouse to 'push' (i can't explain it better than that) the screen to the other side of the LCD panel.

The machine has an SiS630 video card and is running RedHat 7.3 (latest kernel). Everything else about the OS works great (including the video card itself) except this.

Please help if you can, I want to use linux! :(


you can email me: j0ker@daforest.org if you like

you need to alter the section in your XF86Config so it shows
you can have a load of other modes if you want especially if you are not sure whether the new one will work.

you'll find this section near the end of the file

hope that is what you wanted

I've already done that, on all three modes, 8, 16, & 24. I have it setup to use 1024x600 and 800x600, and both resolutions are stretched in ways I don't want. 800x600 fits, but stretches the "800" part to fit the LCD's 1024 width. When in 1024x600 mode, it stretches the screen beyond the LCD, which is obviously incorrect. I wish I could explain it better... am I making any sense at all?

What driver are you using?

There are a option mentionated in the manpages for the SiS video driver included with Xfree86 (man sis):

Option "NoXVideo" "boolean"
Enable or disable use of the video scaler. Default:
off.

I don't understand it use, and the chipsets it support are different from yours, but i think you can try it if you are using the "sis" driver..

Also you can search the JVC or SiS website to see if they have a driver
for your chipset.

Oppsss.... I think you must check this site:

Hope this help . . . . . . ^_^

If what I'm reading is correct, you mean Virtual Screen/desktop?

If that's what you mean, lookie here:

Identifier "Screen0"
Device "nVidia Corporation|NV11"
Monitor "Monitor"

EndSubSection

You see the "Virtual" tag? Reduce it to the maximum size of your screen, 1024x768. So it won't "stretch".

Scroll through the pages and make very sure the desired resolution comes before the others.

Let me know if your screen on CRT is off-center.

Well, I've been trying everything, and yet nothing works. I did, however, go back to RedHat 7.1 and the older version of XFree86 seems to support the configuration *better* but not that well, and 7.1 seems to lack a LOT of things I need in 7.3.

Thanks for everyones help, and please let me know if you think of anything...

since this is quite a peculiar notebook, have you tried the linux-laptop mailing list?

Hi!
Just by the way, I think that XF86 4.x does not use modelines anymore, it makes them automatically on the fly, very nice :)

RefriedBean

No, I haven't... good idea, I should've tried that first.

Oh yeah? I didn't know that, do you know if there are any ways to turn that feature off? It may be what is causing the screen to distort since sometimes the computer seems to ignore what I tell it. (I'd better get to reading those man pages)

Thanks again!

put a hash mark # in front of the offending line or just delete it. I read the man pages for you (i was in that sort of mood) and they are obselete nowadays apparently.

Alex

P.S. you want 'man XF86Config' for all the options in the config file explained to you.

Are you sure that it uses 1024x600 and not 1024x768?

^^^ check that site about the machine. Its a subnotebook.


...
And thanks webtoe, I'll check those man pages too.

Wierd LCD size, have a look on http://www.mobilix.org/ for info.

I had the same problem with my new JVC MP-XP7210. Have a look at:

http://www.winischhofer.net/linuxsis630.shtml

Install the two binaries for the X driver and the DRI module. On my SuSE V8.0 installation it works fine with 1024x600 resolution.

Nice to hear that linux works on JVC MP-XP7210! I am thinking about buying one as well. All I want to know is how difficult the installation is going to be using SuSE V7.2 or V8.0. Is there any problem using a external CDROM? Do I need a floppy drive?
