Hi,

I've been using Debian Jessie for a few weeks, and all has been fine until this afternoon when I noticed that the screen appeared to have frozen on the screensaver. I restarted the box (Dell 7020 i3 intel integrated graphics) and after the grub screen there is a flash of TTY login, then the screen turns black and all keyboard/mouse input fails. The server is still running, as I can SSH in, but local login no longer works. Does anyone have any ideas what I can try? I have tried re-installing xorg and GDM from apt, and can get terminal login back by adding "nomodeset" in grub, but still no x-server. Xorg.log.0 file doesn't show any errors either.

Thanks in advance

To make sure it is not a hardware issue boot with some liveCD (SystemRescueCD is a must tool) and see if X works.

Hi. Thanks for answering. I'll try this later. I've done some more digging, and have found an error in libpixbuf2 which states "g_module_open failed for /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-svg.so: /usr/lib/x86_64-linux-gnul)/libcairo.so.2: undefined symbol: pixman_image_composite32" it's looking like i need to remove/reinstall one or both, but i'm not sure how to do this.

Thanks

edged, i doubt the error message has anything to do with the problem at hand.
how did you get by it anyway?

what you described sounds more like a standard gpu/driver problem (could there have been a system update/upgrade just before the failure?).

what exactly is this "screensaver" it gets "stuck" on?

do what emerson asked.

assuming it works with a live cd/usb, boot back into the command line of the installed linux, enter following command:
and, grep the Xorg log file of both the running and the previous session (*) for EE, with about 5 lines of context.

(*) and no, i don't know which is which. i'd have to look it up on the web first.

The problems that I had on my sid system was gdm3, I was able to startx from root but not the user

So the hardware seems to be reported OK, but with "nomodeset" option in grub, Xorg.0.log shows "no devices detected" and "no screens found".

Booting without "nomodeset" and using SSH to get into the server Xorg.0.log shows

Other than Cyrillic font being missing it looks fairly normal. The oldest Xorg.log seems to have more mod probing, and fails back to a different module that the newest doesn't seem to be doing

Thanks for all assistance so far

Hi Ondoho,

To answer your other question about the screensaver, I had walked upto the machine, and noticed that the standard unlock screen was unresponsive. I reloaded the device and instead of the GUI I got a blackscreen with a non-flashing cursor in the top left corner.

@EDDY1, I've tried launching both gdm3 and kde as root and standard user, but neither gives a GUI environment.

Thanks

edged, i don't understand your previous post.
it doesn't seem to answer my question (what exactly is this "screensaver" it gets "stuck" on?).
anyhow, it begs the question: how did you reload and what exactly did you reload?

about your previous code:
please start without nomodeset, then ssh into the machine and get the output of
and also the most recent Xorg log.
but please, grep for EE, e.g. thus:
and use code tags (see my signature on how to use them).
i'm sure i missed some important info from your last post because it's plain unreadable.

edit:
how new is this machine?
it could be that debian jessie (stable) is not the best distro for it, or that you need a backported kernel.

Hi Ondoho,

Apologies for complicating things!

The restart that I performed was a full system reboot from ssh.

lspci -k shows:-

Xorg.log doesn't really show anything, but I've included the output as requested.

Thanks

everything seems to be in order.
BUT, i'm not so sure if debian jessie's default kernel supports this hardware, hence my question about the age of the machine, which you left unanswered.
some kernel backporting might be in order.

but before you do it, please try to boot the system from a live medium (e.g. usb or dvd), first with a debian stable based distro, then with ubuntu or mint, and see if you can reproduce the problem.

Workin on a laptop that just boots to single user mode right now.
I did an apt-get update & apt-get upgrade & found that /var/cache/apt/archives was full.
