Topic: black screen after upgrades and reboot

Hi,

I tried both openbox and xfce flavours of Statler A2 and it occurs for both : a black screen after reboot. No login screen

regards,

a linux newbie. Thanks

Re: black screen after upgrades and reboot

hello,

what happens if you choose "Recovery Mode" in the boot menu right after starting your PC (thats the second entry, so press Cursor Down and hit Enter)
you should end in normal text mode without graphical environment.
If there are errors you will see what failed.
enter

startx

If the X environment doesn't start up, this is due to the upgrade of the Xserver files (graphics adapter)

Do you know which graphics adapter your PC has? If you dont know, but it is a laptop/net-notebook, just tell us the Type and Model of your PC.

EDIT: Found it in your other post, so it is 'AMD Geode LX 800'. Just for further reference.

http://bugs.debian.org/cgi-bin/bugrepor … =443979#61

A user reported that he failed to install even with custom "CONFIG_FIRMWARE_EDID=n"
kernel, but non-custom installer could work with "video=lxfb:1024×600-32@60"
option.

He uses "Kojinsha SA5ST12A", it has AMD Geode LX800 chip.

(Japanese)

This means that

video=lxfb:1024×600-32@60

probably should be added to the kernel image as (additional) parameter in your GRUB.
You can try it, nothing bad will happen:

- boot up the PC to the Crunchbang GRUB menu
- in the first option, press 'e'
- move cursor down to 'linux /boot/vmlinuz... and go to the end of this line (which is actually its *next* line) where you see "ro quiet"
- there append: video=lxfb:1024×600-32@60
- press Ctrl-X

If this brings you to #!, you can add the "video=lxfb:1024×600-32@60" permanently to your GRUB (GRUB2?) with grub2conf (careful, you better ask for assistance if you don't know what it is)

Good luck!

Edit:) Maybe a fellow Japanese can confirm it? http://mlog.euqset.org/archives/debian-users/53665.html

Re: black screen after upgrades and reboot

Hi

I still have the same unresolved problem as described in my thread:

http://crunchbanglinux.org/forums/topic … nk-screen/

In recovery mode i can see the command line - startx and even a basic xorg.conf (vesa mode ) do not help at all.

Re: black screen after upgrades and reboot

Morgen Tony,

I have read your post. If you like I resurrect your original thread, possibly your PC has a different setup than charmaine's.

Re: black screen after upgrades and reboot

Thanks, machinebacon. Will give it a go

>> you can add the "video=lxfb:1024×600-32@60" permanently to your GRUB (GRUB2?) with grub2conf (careful, you better ask for assistance if you don't know what it is)

I do not know what's this ? Could you provide step-by-step instructions ? Thanks !!

Re: black screen after upgrades and reboot

charmaine,

this additional step (grub2config) is only neccessary if the first instructions (adding the parameter in GRUB menu after booting) had solved your problem smile

After pushing Control-X, it goes back to black screen

Re: black screen after upgrades and reboot

ok, we try something else:

let the line end with:

ro video=lxfb vga=771

or


ro video=lxfb

another try would be:

lxfb.mode_option=1280x1024

I pray, too wink

Re: black screen after upgrades and reboot

Does your livecd crunchbang work on your computer?

This website http://webdt.org/index.php?topic=549.0  recommends to use "video=ofonly acpi=force”  as a addition to your kernel. They also recommend Debian 5 or OpenSuse 13.1 as the best distros for Geode LX 800.  Note: The crunchbang version you are using is using debian. 

Kernel option to try    video=ofonly acpi=force
 
If you find something that works by adding a addition to your kernel and you have booted your computer up, here's a method to make that method permanent.

Example of setting up a  permanent kernel option
open a terminal
sudo gedit /etc/default/grub
#GRUB_CMDLINE_LINUX=""     Change this to
GRUB_CMDLINE_LINUX="video=ofonly acpi=force"
save file
open terminal and type  "sudo update-grub"
reboot

Re: black screen after upgrades and reboot

;-( no good...  http://uppic.net/full/a4a2dd5300d4f176a5392c9426fb0914

still goes into a black screen

Re: black screen after upgrades and reboot

I have the same problem as Charmaine. The screen goes black around the time I'm used to GDM coming on. This is #! Statler XFCE on a Packard Bell TM-85 laptop (Intel Core i3 processor and Radeon HD5470 graphics card). I think I've installed the proprietary driver too.

I've tried starting #! in recovery mode and then typing startx. Some messages flash by, but I have no chance of reading them before the screen goes black. And then nothing.

This first happened yesterday.

Re: black screen after upgrades and reboot

My laptop just did the same thing last night after a fresh install of CB OpenBox and then an upgrade. Like others, the screen goes black just as the GDM is starting.  I'm able to ctl-alt-F1 to get to a console however. Also, I can actually get into X perfectly if I boot into recovery mode via GRUB and start the GDM manually. Is it possible to reconfigure X like you do after doing a fresh install and initially booting?

Great community and a wonderful distro. Thanks to all who contribute.

Re: black screen after upgrades and reboot

Happy to report that adding machinebacon's GRUB line allowed me to boot normally. Many thanks.

video=lxfb:1024×600-32@60

Re: black screen after upgrades and reboot

I don't like using fixes that I don't understand, to a bug I don't understand. Can someone please tell me what lxfb is and why I should enter those particular values?

Also, this isn't a permanent fix is it? Does anyone know if this problem is recognised and being looked into upstream? In that case I'd rather try to get online via the shell and do updates til it works.

Seems it has been fixed, so that's what I'll do: http://crunchbanglinux.org/forums/topic … e-upgrade/

I actually don't quite understand the resolution. Can someone provide step-by-step on how to implement this fix ? Thanks

Re: black screen after upgrades and reboot

Hi,

I also had the same issue with getting a blank screen instead of a login splash page after upgrading Debian Squeeze, but it was due to incompatibilities with the proprietary ATI/AMD fglrx driver. I followed the instructions from https://wiki.ubuntu.com/X/Troubleshooti … deonDriver to totally remove the proprietary fglrx driver using the Recovery Mode CLI and reinstall the open-source ati radeon drivers (libgl1-mesa-dri). Btw my ati/amd card is an HD3450 (R600) which used to not be supported by the mesa drivers; today, however, the card is quite well supported!
At the command line type the following:

sudo /usr/share/ati/fglrx-uninstall.sh  # (if it exists)
  sudo apt-get remove --purge fglrx*
  sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon 
  sudo apt-get install xserver-xorg-video-ati
  sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
  sudo dpkg-reconfigure xserver-xorg

After a "shutdown now -r" to reboot, X starts up with no problems!!! Hooray! Unfortunately once I logged in, I didn't have any networking! Thankfully, some searching in the forums turned up this thread: http://crunchbanglinux.org/forums/topic … plet-gone/, and after re-installing "network-manager-gnome" from the .deb I downloaded onto a USB stick, I was good to go.

Anyways, I would like to thank all the knowledgeable peeps on the CB forums as well as Corenominal for making CB Statler! The upgrade snafus due to Squeeze testing aren't his fault, and I've found Statler A2 to be much more stable than CB 9.04 on Jaunty!

Cheers,
-Jun

@ jelli
fine at last
Finally the intel-video-driver is working again with the new updates (kernel, xserver, intel-driver) - if anybody was waiting as patiently as i.

charmainelooi,

According to link you are looking at, there was a incorrect function name placed in the code that was downloaded during your update.  According to last post by jelli, this has been fixed in the last update which includes a new kernel, xserver and intel-driver.  You need to do another update.

sudo apt-get update
sudo apt-get dist-upgrade
