Ubuntu no display after loading screen.

shady_inc · Jan 29, 2008

Just yesterday, I was playing around with compiz-config settings manager and did something which I now feel I shouldn't have done.Anyway, I restarted the X-windows [Ctrl-Alt-Backspace] and I haven't been getting any display since then.The loading screen appears but a message "Input Not Supported" flashes across the screen while loading and there is no display after that.Here s my xorg.conf file:

Type this command

Code:

 grep EE /var/log/Xorg.0.log >> xorg_errors.txt

It will create a file xorg_errors.txt, upload it here.

gary4gar · Jan 30, 2008

remove this wacom sh!t & whenever your X fails, first try

sudo dpkg-reconfigure xserver-xorg

praka123 · Jan 30, 2008

@shady:Isn't gutsy uses driver "intel" rather than "i810"

so,it will be:

Code:

Section "Device"
    Identifier    "Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device"
    Boardname    "Intel 845"
    Busid        "PCI:0:2:0"
    Driver        "intel"
    Screen    0
    Vendorname    "Intel"
EndSection

also ur xorg.conf seems a custom one that is not generated by dexconf

still no display?press ctrl+alt+f2 to and login.then run "sudo /etc/init.d/gdm restart"

adi007 · Jan 30, 2008

AFAICR UBUNTU(nearly every distro) will make a backup of the xorg.conf before any changes are made..
search for it it might have extension xorg.conf.bak or something..
once it happened to me and i just backed up the file and then everything was allright..
remember u have to have root privilages...just log in emergency console or enter single user mode and do it..
the backup file will be in the same directory..
just type

Code:

cp backupfilename xorg.conf

Hi.!
@ mehulved: Here is the content of that file:
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(II) Loading extension MIT-SCREEN-SAVER
(EE) intel(0): detecting sil164
(EE) intel(0): Unable to read from DVOI2C_E Slave 112.
(EE) intel(0): Unable to read from DVOI2C_E Slave 236.
(EE) intel(0): ivch: Unable to read register 0x00 from DVOI2C_B:04.
(EE) intel(0): Unable to read from DVOI2C_E Slave 112.
(EE) intel(0): tfp410 not detected got VID FFFFFFFF: from DVOI2C_E Slave 112.

@gary4gar: I tried that command, but it asked for several things like:
Rather than communicating directly with the video hardware, the X server
may be configured to perform some operations, such as video mode switching, via the kernel's framebuffer driver.
In theory, either approach should work, but in practice, sometimes one
does and the other does not. Enabling this option is the safe bet, but
feel free to turn it off if it appears to cause problems
I have no idea what to select here.So I just shut down the terminal at this point.

@praka123: I have selected intel i845 under Screen & Graphics.It still shows the driver as 810.
That's how it has always been.[checked in earlier backups too.It was i810 rather than Intel.]

@adi007 :shock:

.There are 7 backups of xorg.conf under /etc/X11.!
BTW, I am able to boot into ubuntu,like, say every 1 out of 5 times.I managed to get Ubuntu display today morning.But when I check back in the evening,it's back to blank screen.;(.It's not the LCD getting old or anything since both Vista and Ubuntu LiveCD work fine.

@shady:do a

Code:

sudo dpkg-reconfigure `uname -r`

and may be a

Code:

depmod -ae

also when internet is connected,do a :

Code:

sudo apt-get update && sudo apt-get upgrade

then,

Code:

sudo apt-get install libgl1-mesa-glx libgl1-mesa-dri mesa-utils  xserver-xorg-video-intel

the xorg.conf generated by gutsy seems similar to the ones from fedora and other rpm distros :twisted:

I think the display fails may be due to the resolution which the monitor/LCD cannot handle due to the modesetting options given by xorg.conf you used in ubuntu.So,
use the below /etc/X11/xorg.conf as it is :

remember,use "intel" driver must be used instead of old "i810" drivers for support.Just installed Gutsy Ubuntu on an intel machine 2 days back,so knows the thing

Code:

# xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

^ur vertical and Horizontal resolution also is wrong.So,I used the correct frequencies as per Hcl website.

*www.hclinfosystems.in/HCM510LSA BROUCHURE rev 01.Doc

restart gdm(sudo /etc/init.d/gdm restart or "telinit 1+ CTRL+D in runlevel 1") for the X to set correctly.

Now,In GNOME,go to menu System>Preferences>Screen Resolution to 1024x768@60Hz(recommended Resolution as per HCL site) or 1024x768@75Hz for ur 15" LCD Monitor

If u have enough RAM there,try enabling compiz also in Ubuntu

@adi007 .There are 7 backups of xorg.conf under /etc/X11.!

there is nothing to shock as i said everytime u change some display settings the backup file will be created..
if there is some number in the name of the backupfile then restore the file with higgest number in it's name..
else if u are confused,restore any file u like..I am sure it will work...
to restore file use root authentication and issue

Code:

cp backupfilename xorg.conf

I strongly believe this will work ..try it...

If Ubuntu Live cd works fine , then just copy the xorg.conf from the live cd to ur original xorg.conf.

Hi.!
Now I can boot into Ubuntu alright.!

Did almost everything mentioned here.Not quite sure what worked and what didn't.But everything looks to be fine for now.I might as well re-install Ubuntu to undo any harmful changes I might have made.

praka123 said:

I already run it without any problems, even when the driver was set to older "i810"

And I have also managed to convince two of my friends to install Ubuntu after a little "Compiz Fusion Showdown"

Ubuntu no display after loading screen.
