Xdsl Screen Res Or Something, help please Options

[friedgold]

However I can not find the file XF86Config-4 mentioned below. I'm not really advanced in this so if anyone knows if there's a way to alter console video "modes"..... please help!!

You won't find a XF86Config-4 file because X-DSL doesn't use one. Basically the situation is this: gentoox/xebian use the XFree86/X.org X servers. They access the video hardware directly and so need a seperate config file telling them what video modes to use. X-DSL (and sXb mini I believe) use the the K Drive framebuffer X Server. This doesn't access the hardware directly but uses the framebuffer instead. This means all you need to do is get the video settings working on the framebuffer with fbset and the X Server will use these settings too. Once everything looks good just save the fbset command you used to a init script so it is run every boot.

i get a greenish screen on my hdtv with hd pack... have tried some of the suggestions to change res. but never worked... too bad!

[ronaldraygun]

Do you have a HDTV? 480i doesn't work with component - only 480p and 720p are support using the hd pack. On v1.6s I think only 480p works. Also cromwell has some issues with HDTV + certain Xbox versions - you might want to give the gentoox loader a go to see if that's any better. I think s-video works but I'm not certain (and I've got no way of testing it here anyway).

its not an hdtv, and i have a 1.o xbox. Can you link me to any info on this gentoox loader? i want to find a way to work with this hd-pack because the normal video pack sucks horribly, its real blurry and out of focus fonts are real hazy. Would the s-video look any better or is it due to the res?

[friedgold]

I'll say it again:

480i doesn't work with component

i.e. you can't use the hd-pack without a hdtv. This is a limitation of the current kernel in X-DSL and the bootloader will make no difference. If you are trying to use the hd-pack with a hdtv then the gentoox loader may help in some cases and is available from shallax's site.

Hi,

I wasn't sure whether to start a new thread or not so I didn't.

Anyhoo...

When running xdsl on my TV, my display is bad. I'd like to run it at 720p, but the bottom and sides are cut off.

I've read many faqs and tutorials, I've edited the linuxboot.cfg for pretty much every screen size, and I've tried using fbset.

I know that xdsl does not have an x config file and that I must make the changes via fbset, but in my searching, I found a post (herehere) where someone had altered the modeline for the "X config file" for my exact tv, and claimed that it worked properly.

I have tried editing fbset, but I have always ended up with an orange, unreadable screen. (I don't have all of the combinations I tried here, but I can post them when I get home). I made sure my height and width were divisible by 8, and that the sum of the horizonal + margins and vertical + margins was the same after my modifications as it was before...

Anyways, I just found the following info and am wondering if there is a way to translate it into something could could put into fbset. These settings are reported to work for my tv, and if I could adapt them to my needs, I'd be a happy man.

Modeline "1280x720" 74.48 1280 1336 1472 1664 720 721 724 746 -HSync
+Vsync

Monitor/TV: Olevia 27" Widescreen (16:9) HDTV (480p,720p and 10801i compatible)

Thanks for reading!

PS: I can't remember my xbox version, but I i know it's not 1.6.

ok look i dont have much linux skills but i do have a USB keyboard and the overscan is HORRIBLE on my tv. So I haven't really understood what to type to change the res. So can anyone help.



Thank You

Anyways, I just found the following info and am wondering if there is a way to translate it into something could could put into fbset

fbset -x shows the xfree86 compatible video settings. By playing around with this they seem to be in the form:

CODE

DotClock dotclock
HTimings xres (xres+left) (xres+left+right) (xres+left+right+hslen)
VTimings yres (yres+vslen) (xres+lower+vslen) (xres+upper+lower+vslen)

The pixclock is measured in pico seconds so dotclock=1E12/pixclock.
Therefore pixclock=1E12/dotclock.

Therefore Modeline "1280x720" 74.48 1280 1336 1472 1664 720 721 724 746 translates to

geometry 1280 720 1280 720 32
timings 13426 56 136 22 3 192 1

or

fbset -g 1280 720 1280 720 32 -t 13426 56 136 22 3 192 1

(If my reasoning is correct anyway)

fbset -g 1280 720 1280 720 32 -t  13426 56 136 22 3 192 1

(If my reasoning is correct anyway)

so i would type that ^^^?

Hey friedgold,

Muchos gracias -

I'll try it when I get home tonight. I'll be eternally grateful if it works!

Hey st3ph3nt4n,

The answer above was addressing my specific TV (hopefully). For your setup, before you go messing around with fbset, make sure you've tried out some of the different screen resolutions in the linuxboot.cfg file.

There's a few different screens that are supposed to work - check the CHEATCODES.txt file that came with your install.

Hey friedgold,

I wanted to let you know that your fbset worked (mostly). I think the left and right margins got flipped in your calculationse, so I flipped them and tweaked it a bit and it seems to work now.

(In case anyone else is setting up up syntax olevia 27", try this:
fbset -g 1280 720 1280 720 32 -t 13426 156 36 22 3 192 1
)

A couple more noob questions...
Do I have to type this every time I want xdsl? When I restart my xbox, it uses the settings in the linuxboot.cfg file (not fbset). If I remove the video info from linuxboot.cfg file, I get a warped squished-double-screen thing happening... There must be some way I can permanently apply fbset? Should I leave the video=xbox:720p in the cfg file?

Also - using the fbset above, the picture isn't as nice as the 720p. Don't get me wrong - I'm thrilled that it now fits on the desktop , but if someone could tell me how that modeline to fbset was done, I might like to recheck the math...

Add the fbset command you needed into one of the startup scripts. The easiest place to add it is probably /opt/bootlocal.sh. If you using a frugal install you will also need to make a backup file (not necessary with loopback/native). Then your settings well be applied every time X-DSL boots.
