3. active screen, enter password, login system again
4. lock screen again with command 'dm-tool lock'
what happend:
screen remains blank, can not active screen.this happens everytime if I
take actions described above.
I'm using Archlinx + lightdm + lightdm-gtk-greeter, laptop X1 carbon

[LightDM] Can not active screen after second time lock screen.
Hi, You should have a look in /var/log/lightdm/lightdm.log. This should give you more idea which part is failing. If that is fine and the error in the X log is significant this is probably an X / driver issue. --Robert On Tue, 12 Apr 2016 at 08:01 Hacksign <evilsign at gmail.com> wrote:> what I have done: > 1. login system > 2. lock screen with command 'dm-tool lock' > 3. active screen, enter password, login system again > 4. lock screen again with command 'dm-tool lock' > what happend: > screen remains blank, can not active screen.this happens everytime if I > take actions described above. > > I'm using Archlinx + lightdm + lightdm-gtk-greeter, laptop X1 carbon 2015 > edition. > > there is a failure in /var/log/lightdm/x-0.log : > [root at XSign lightdm]# cat x-0.log > > X.Org X Server 1.18.3 > Release Date: 2016-04-04 > X Protocol Version 11, Revision 0 > Build Operating System: Linux 4.2.5-1-ARCH x86_64 > Current Operating System: Linux XSign 4.4.5-1-ARCH #1 SMP PREEMPT Thu Mar > 10 07:38:19 CET 2016 x86_64 > Kernel command line: initrd=\initramfs-linux.img root=/dev/sda3 rw > Build Date: 05 April 2016 05:24:02PM > > Current version of pixman: 0.34.0 > Before reporting problems, check http://wiki.x.org > to make sure that you have the latest version. > Markers: (--) probed, (**) from config file, (==) default setting, > (++) from command line, (!!) notice, (II) informational, > (WW) warning, (EE) error, (NI) not implemented, (??) unknown. > (==) Log file: "/var/log/Xorg.0.log", Time: Tue Apr 12 13:45:41 2016 > (==) Using config directory: "/etc/X11/xorg.conf.d" > (==) Using system config directory "/usr/share/X11/xorg.conf.d" > xf86: remove device 0 /sys/devices/pci0000:00/0000:00:02.0/drm/card0 > failed to find screen to remove > (II) AIGLX: Suspending AIGLX clients for VT switch > > below is my lightdm.conf: > [root at XSign lightdm]# cat /etc/lightdm/lightdm.conf > #
