Public bug reported: As suggested by ubuntu an upgrade was started from 16.04 to 18.04. Although it was a 32-bit upgrade and release notes tell 32-bit is not possible anymore, this upgrade succeeded. But at the restart the login page was not shown and mouse/keyboard did not work.
Probably the problem was caused by the error at syslog: Aug 19 23:34:11 gert-laptop org.gnome.Shell.desktop[959]: glamor: EGL version 1.4 (DRI2): Aug 19 23:34:11 gert-laptop org.gnome.Shell.desktop[959]: Require OpenGL version 2.1 or later. Aug 19 23:34:11 gert-laptop org.gnome.Shell.desktop[959]: Failed to initialize glamor Aug 19 23:34:11 gert-laptop org.gnome.Shell.desktop[959]: Failed to initialize glamor, falling back to sw Surprisingly login was possible by using recovery mode, then start "network" and finally pressing Ctrl-C. Ubuntu was running successfully, but the external monitor was ignored. Version of OpenGL seems to be 3.0: glxinfo | grep OpenGL OpenGL vendor string: VMware, Inc. OpenGL renderer string: llvmpipe (LLVM 6.0, 128 bits) OpenGL core profile version string: 3.3 (Core Profile) Mesa 18.0.5 OpenGL core profile shading language version string: 3.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 18.0.5 OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.0 Mesa 18.0.5 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00 OpenGL ES profile extensions: Problem could be solved by using one of the other *ubuntu's or the ugly xfce4, I tried. The most simple solution is reconfigure lightdm to use display manager lightdm instead of gdm3 by starting : dpkg-reconfigure lightdm. Ubuntu now works. Version of OpenGL now seems to be 1.4 (same as at 16.04 release): glxinfo | grep OpenGL OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) 945GM x86/MMX/SSE2 OpenGL version string: 1.4 Mesa 18.0.5 OpenGL extensions: OpenGL ES profile version string: OpenGL ES 2.0 Mesa 18.0.5 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16 Also the dual screen problems from 16.04 seem to be completely solved now.
