Description Michael Helmling 2006-07-19 07:26:18 UTC
First Xorg didn't start at all, but as shown here http://bugs.gentoo.org/show_bug.cgi?id=140915 I was able to fix this.

But x-setup didn't get the right resolution (I have a widescreen laptop with 1280x768 pixels, and it's set to 1024x768), and it didn't choose the right driver (using vesa instead of i810, since it's an Intel 915GM chipset. Interestingly, as gentoo tried to configure X itself and failed, it wanted to use the i810 driver:

(EE) Failed to load module "glx" (module does not exist, 0)
(WW) I810: No matching Device section for instance (BusID PCI:0:2:1) found

Fatal server error:
Cannot run in framebuffer mode. Please specify busIDs for all framebuffer devices.


Also there's something wrong with vertical refresh. The screen flickers a bit, and in Xorg.0.log:

Attempting to use 75Hz refresh for mode "1024x768"

But the laptop panel supports only 60.

If I change the according sections in xorg.con (driver to i810, modes to "1280x768" it looks fine.
Comment 1 Chris Gianelloni (RETIRED) gentoo-dev 2006-07-19 07:41:24 UTC
The LiveCD doesn't do video mode detection.  It is *always* 1024x768.

The CD should have chosen the i810 driver, except that I forced it to VESA because i810 ends up so broken.  If you don't believe me, look at the countless Intel video bugs from the last release.

Now, could you provide the actual failure information from what the CD itself tried to do and *not* from what you tried to do?  It shouldn't be failing on attempting to load/use the VESA driver.

Comment 3 Chris Gianelloni (RETIRED) gentoo-dev 2006-07-19 13:33:02 UTC
"(EE) Unable to locate/open config file"

OK.  So this was one with the broken X.Org configuration scripts.  That was exactly what I needed to know.

Comment 6 Stefan Kienzl 2006-07-20 12:10:31 UTC
sorry for the doubled and broken xorg.conf post

well, this file is generated by /etc/init.d/x-setup and if I start X, I get a totally scrambled screen (the right end is on the left side). If I switch back to the cli I also have this scrambled screen. You can't work with this because you are unable to read the text on the screen

if you like, I can upload my functional xorg.conf from my working gentoo
Comment 7 Chris Gianelloni (RETIRED) gentoo-dev 2006-07-20 13:04:46 UTC
There's no need to upload it.  We auto-generate the configs, so there's no way ours will end up exactly like yours.  How much video RAM do you have allocated to the on-board video?

(Did I mention I hate Intel video chipsets? :P)
Comment 8 Chris Gianelloni (RETIRED) gentoo-dev 2006-07-20 13:06:05 UTC
I'm about to commit a change which will make some changes to the X detection.  The next LiveCD release should have these changes.
Comment 9 Stefan Kienzl 2006-07-20 13:34:51 UTC
my videocard currently uses 8mb shared memory - notebook is an acer travelmate 621 lv
I know that nowadays most livecd can set up a correct xorg.conf for my stupid video card, so I hope gentoo would do this soon too.

(well, since i have always an ugly black edge and only 1280x1024 instead of 1400x1050 I hate intel chipsets too ;-)
Comment 10 Chris Mortimore 2006-07-20 23:58:49 UTC
This might be related, I'm not sure, but here goes:

I just booted the livecd in vmware and have got the following errors from xorg:

...
New driver is "vmware"
(==) Using default built-in configuration (53 lines)
(EE) Failed to load modules "glx" (module does not exist, 0)
(EE) Failed to load modules "vmware" (module does not exist, 0)

Err... *which* LiveCD?

Please remember that we are updating this thing at a pretty quick pace, so please give the MD5 of the CD you've tested, or else we can't track the changes easily.

Thanks... =]
Comment 12 Stefan Kienzl 2006-08-02 09:30:09 UTC
I've tried booting with
# MD5 HASH
e9e7dbcefea1d2e2de85b6c12bd652c0 livecd-i686-installer-2006.1.iso
but my screen is still completely scrambled. I've found a workaround to get a "normal" screen you can work with. 

I had do increase the X reolution from 1024x786 to 1280x1024. Is there a chance to get this automatically set or do i have to set this always by hand because you would always set the resolution to 1024x786?
Comment 13 Andrew Gaffney (RETIRED) gentoo-dev 2006-08-02 11:20:46 UTC
This sounds like a request for bug 104153 :)
Comment 14 Stefan Kienzl 2006-08-02 11:38:53 UTC
yes, this seems to be a request for bug 104153 :-)
Knoppix has this "fb1280x1024" boot option and this works just fine for me. So there should be a boot option to set the X resolution to more or less then 1024x786
Comment 15 Chris Gianelloni (RETIRED) gentoo-dev 2006-08-03 11:48:36 UTC
Eventually, there will... but not this release... there simply isn't enough time.
Comment 16 Chris Gianelloni (RETIRED) gentoo-dev 2006-08-23 09:07:25 UTC
Removing RTx86 since this will affect final release media, too.
Comment 17 Chris Gianelloni (RETIRED) gentoo-dev 2006-09-25 14:24:49 UTC
OK.  We have updated the 2006.1 LiveCD with a new kernel on the mirrors.  Can you check and see if it resolves this issue for you?
Comment 18 Stefan Kienzl 2006-10-01 04:41:17 UTC
still get the same ugly scrambled screen with the new version 
# MD5 HASH
f46c9bcadea4944396f6ecdd7dbf283c  livecd-i686-installer-2006.1.
Comment 19 Chris Gianelloni (RETIRED) gentoo-dev 2006-10-02 09:10:45 UTC
Stefan, I was referring to the original bug reporter.  Your issue is different than his and really doesn't belong in this bug.
Comment 20 Chris Gianelloni (RETIRED) gentoo-dev 2007-05-10 18:40:20 UTC
Michael, can you try 2007.0 and tell me if it works for you?
Comment 21 Chris Gianelloni (RETIRED) gentoo-dev 2008-02-26 04:43:07 UTC
No response...
