Post subject:  TV screen totally messed up after KnoppMyth installation
Hi,

I've just installed KnoppMyth on an old PC I want to use as media center.

So this PC is connected to a TV, not a monitor.

Installation runs fine, but when finished, at reboot the screen is totally messed up in X mode, I can't see anything on TV but black, white and blue diagonal stripes.

I can access terminal mode with ctrl+alt+f2, but the graphic mode doesn't work.

I tried to search infos about this on google, but documentation available it's totally confusing and contradictory. I tried many and many options in xorg.conf suggested from many wikis and "How To", but the TV-Out still doesn't work.
I find many sites suggesting to set some options in the "device" section, but they never specify for which card and drivers these options are, so it was just a long long waste of time. :(

So finally I decided just to reinstall KnoppMyth again: now I've got the default xorg.conf file on a clean install.

ATI Radeon 9000 Pro ViVo.
KnoppMyth R5F27
xorg.conf is the default one, except for the hsync and vsync lines (set to hsync 30-50 and vsync 60, but still gettiong unwatchable screen)


So what should I do now to get it working? :(
Please help! :oops:

Start by looking at the logfiles:
http://www.knoppmythwiki.org/index.php?page=CheckingLogFiles

You're looking for errors (lines marked with an '(EE)', and warnings '(WW)', but also for which driver it's using, what resolution/color depth, and what modeline. The ATI drivers can be fiddly to get working, so falling back to something else like the svga or vesa driver first may make things easier.

These ATI driver instructions are slightly out of date (the drivers are now included in the install), but you may get some pointers on setting up your xorg.conf from them.

When I started to install KnoppMyth, I figured out it was a sort of "plug and play" software, I didn't guess it would became such a pain :(

So... I found the log. There are some WW but no EE lines.
It tells that the driver is
"ATI driver (Version 6.6.3) for chipsets: ati,ativga"

So you think that I should change them? :?


Thanks for your help; really appreciated.

I tried to follow instructions in http://www.knoppmythwiki.org/index.php? ... +Video+Out, but it doesn't work :(

aticonfig --initial --overlay-type=Xv fails with:

error while loading shared libraries: libfglrx_pp1: cannot open shared object file. No such file or directory.


What the hell does this matter? :shock:


I'm searching a lot for installing vesa or svga driver, but I can't find anything much useful..... How should I install them? :oops:

The vesa driver is a built in one. To use it, look in xorg.conf in the Device section, and change the driver line to:

Driver "vesa"

It is if you stick to well proven hardware. This is what the Tier 1 and Tier 2 Hardware Recommendations topics are all about, and why I wrote this posting which Cecil made sticky so it would get noticed: http://mysettopbox.tv/phpBB2/viewtopic.php?t=6321 and the (slightly out of date but still relevant) hardware configuration pages on the wiki: http://www.knoppmythwiki.org/index.php?page=PickingComponents and ...

It always pays to do your hardware research and figure out what kind of tweaks will be needed before setting up your system and starting the install. ;-)

As mad_paddler indicated both the svga and vesa drivers are already installed, you just need to tell X to use them for your video card as he described.
Code:
Section "Device"
        Identifier  "Card0"
        Driver      "vesa"
        VendorName  "All"
        BoardName   "All"


BTW - You never told us about the other stuff I said to look for. Having the driver pick an inappropriate resolution/modeline for TV output is one of the most likely causes of this kind of problem.

Oh, and the shared library error matters because it's telling you that it can't find a loadable component it needs. Kind of like not being able to find your pants when you're getting dressed. ;-)
