Video "Out of sync"

[carlo...@gmail.com]

Hi. I'm testing Webconverger on some computers. On my notebooks it
works fine, while on desktop (Hp Workstation xw4200 and xw 4600, Acer
Aspire, and other) I get always "Out of range" or "Out of sync". That
happens on all monitor I tried, Lcd or Crt.
With usb or cd boot, I can see the Debian logo, the menu and Linux
loading messages; before Firefox starts, the screen blanks.
Can someone help me?
Thanks

Hi there,

Try forcing a lower resolution, like: xvideomode=1024x768 on the Grub
boot loader.

http://webconverger.org/boot/

Kind regards,

Thank you for the answer. Now I have tried changing resolution to
1024x768, 800x600 and 640x480, with same result. I tried this on a 5th
computer. It seems strange to me I'm the only one with this problem
(on ALL desktop pc I tried).
Any idea?

Does Ubuntu live detect your screen better?

Could you please try the latest daily build on
http://build.webconverger.org/ and report if the situation is any
different.

I sometimes fear `vga=791` on the linux cmdline could b0rk some
computers. However it's rather rare and I would get complaints again
from some people that they can see text on the screen and that scares
them. ;)

Kind regards,

1 - Yes, Ubuntu live detects the screen and I cau use it in normal
mode.
2 - No, also with last build (http://build.webconverger.org/mini.
2009-03-30.4.3-usb.img) the screen is "Out of sync"

Update:
I tried running Webconverger on a HP desktop with a 21" lcd monitor.
Now I can see that graphical environment (Firefox) starts at 1600*
1200 * 59.9 hz. This way, most 17" lcd cannot sync.
The vga=normal parameter, used in fail safe mode, seems to have no
effect on the x "firefox" resolution.
How can we change this resolution?

Have you tried adding xvideomode=1024x768 ?

[carlo...@gmail.com]

Yes, I tried xvideomode=1024x768 and xvideomode=800x600.

I tried also installing on hd to gain access to xorg.conf. After
installation, I see the Webconverger logo and the orange bar stopped
at 70%. This happens on one of my pc, and also on Vmware machine.
It seems impossible for me to use Webconverger....

I also had this issue on 4.x

Will test 4.4 now and see if there is a fix.

[carlo...@gmail.com]

No, Ben, it's the same in 4.4 also. Do you have this problem in 4.x
versions only?

Kai, could I try an older version? I saw you deleted older versions on
download site.

[Kai Hendry]

I will setup an archive site today. :)

Hi Carlo,

Checkout http://archive.webconverger.com/ for old versions.

Hi,

FYI, I had the same kind of problem installing Webconverger on B202
EeeBox.
I was getting this error : "sdvo output reported failure to sync"
It is a known bug with the Intel driver :
http://forums.opensuse.org/hardware/391937-intel-mobile-965-gm-lcd-black-screen.html
For it to work I had to modify the /etc/X11/xorg.conf file by hand
adding the following lines :
Section "Monitor"
Identifier "LVDS"
Option "Ignore" "true"
EndSection

Section "Device"
Driver "intel"
Identifier "card0"
Option "monitor-LVDS" "LVDS"
EndSection

If you do that you'll also have to modify the /etc/rc2.d/
S20webconverger script so that it doesn't overwrite the xorg.conf file
at each reboot.

Note that default webconverger installation does not provide any
editor, thus to modify files I had to boot from the USB key in repair
mode, mount the hard drive and copy the nano editor to disk.

Hi,

I'm also facing this problem.
One thing to check is that when booting from hard drive, the hostname
is set to webconverger in /etc/hostname, otherwise the /etc/rc2.d/
S20webconverger script will silently fail and stop the bar
progression.

I still have to test that but I think another problem may come from
the /etc/inittab file since the one used when booting from the livecd
contains lines like this one :
1:2345:respawn:/bin/login -f webc </dev/tty1 > /dev/tty1 2>&1
Whereas I'm quite sure that the one on the hard disk does not contains
the -f webc option (My test machine is not here, so I can't tell for
sure).
If this is the case and if I understand webconverger's boot process
correctly, that would explain why X would not start since it is
launched by login in as webc user.

Regards.

I wish I had the bug number. Not sure what the actual bug is of this lot:
http://bugs.freedesktop.org/buglist.cgi?quicksearch=LVDS

I'm reluctant to provide any workaround. One idea I had was if you
customise Webconverger with a homepage like:
http://example.com

From example.com it will look for a http://example.com/xorg.conf to
copy into /etc/X11

Well if you boot up in debug mode (removing nosudo from grub boot
line), you can just `apt-get install vim`.

Well, you shouldn't change the hostname. :)

But seriously, this is in place to avoid any silly things like the
init script running on normal systems if people install
webconverger-base on their Debian systems like so:

Are you trying to change the username? Why?

Well that's a good advice ;-)
What happened is that I installed Webconverger on my HDD using the USB
key image and during the installation process I was asked for a
hostname and this is why the hostname was changed.

No, not at all, I'm just trying to find why the progress bar is not
progressing normally...
And I noticed that when booting from a live CD the initab is not the
same as the one on my HDD as explained above.
I made some tests tonight and what is strange is that disabling the
splash screen from the command line makes webconverger work properly
and I have very hard time trying to find what is wrong or even at what
point webconverger stops when the splash screen is enabled.
BTW, I also noticed a few glitches when installing on a HDD, e.g. the
webconverger script is updating the proxy configuration on each reboot
and storing it in the browser configuration file, thus I end up with a
configuration file containing several times the same proxy
configuration line, but I don't know how this could be delt with
during the installation process.

I tried that but it didn't work, but I'm not very comfortable with
Debian so I have no clue why this is not working properly.

Several bug reports are related to this problem like 11455 and 20241

Yes, you're right. The hard drive install Webconverger is a bit
neglected. I should have a new netbook soon to test this feature out
more thoroughly.

I just blogged btw http://webconverger.org/blog/entry/Security_and_privacy/

I hope you all are already subbed on
