Good day or whatever,
since an Debian 9 update some weeks ago, I have the problem, that my Desktop (XServer + FVWM) is unexpected blanking.
I have always to use <Ctrl><Alt><F1> and then <ALT><ARROW_LEFT> to get my Desktop back only that it start blanking again in non regular intervals...
I am using already
xset -dpms s off s blank
since quiet a while on my ThinkPad T400 and had NEVER a problem for years, but it seems, Debian has introduced a new bug in an update.
Anyone here which has the same problem?
Note: My T400 has multiboot and Debian 7+8 (I use the Laptop for Software Development) are working perfectly without any problems. Also I can install Debian 9.2 (from DVD) and the error is gone.
Any suggestions?
Thanks in advance
Michelle

Re: XServer + FVWM is blanking unecpected
It just happen again and I get in my syslog only:
There is nothing more.
Xorg.0.log has
My xsession.log does not show anything either.
First I was thinking the T400 is broken (backlight), but since I could switch to the VT and see it, it is clear software error which trigger this behaviour
It seems, the last line was me while switching to the console and back...Aug 12 23:17:41 t400 courierd: Purging /var/lib/courier/msgs

Re: XServer + FVWM is blanking unecpected
You probably should run command dmesg as root, e.g. . It is command, which writes you kernel ring buffer, which usually contain much more information about errors than syslog...
Code: Select all
sudo dmesg

Re: XServer + FVWM is blanking unecpected
Good morning,
I use already
xset -dpms s off s noblank
since quiet a while and the out put is
First I was thinking, that the Display/Controller of my ThinkPad T400 is broken, but since I can switch to the Console and back to FVWM Desktop, a mechanical or electrical failur is excluded. Also my Debian 7 and Debian 8 installations plus Debian 9.2 from DVD is working.
This Error appeared for me in Debian 9.8.
(I upgraded from 9.4 to 9.8)
Thankyou for your help
Michelle
