Thank you for indicating the bug as confirmed. Some developments: A) i could find how to switch from one environment to the next. Conclusion: problem is independent from gnome/unity/ whatever. B) i created a test account "testacct" and could see the same problem occurring. Conclusion: the session management is not to blame, nor existing user files. C) i copied the dmesg messages. It seems there is a problem with the graphic card. But i can't really say more. For what I want i would be happy to have the graphical user interface working but slow. Any help in resolving the problem would be much appreciated. Mathieu PS: the dmesg output with the first line truncated. generic (buildd@lgw01-amd64-039) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #21-Ubuntu SMP Tue Apr 24 06:16:15 UTC 2018 (Ubuntu 4.15.0-20.21-generic 4.15.17) [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-4.15.0-20-generic root=UUID=79f3e8e1-2b59-4e02-beda-f54ac33825f9 ro acpi_rev_override quiet splash vt.handoff=1 [ 0.000000] KERNEL supported cpus: [ 0.000000] Intel GenuineIntel [ 0.000000] AMD AuthenticAMD [ 0.000000] Centaur CentaurHauls [ 0.000000] x86/fpu: Supporting XSAVE feature 0x001: 'x87 floating point registers' [ 0.000000] x86/fpu: Supporting XSAVE feature 0x002: 'SSE registers' [ 0.000000] x86/fpu: Supporting XSAVE feature 0x004: 'AVX registers' [ 0.000000] x86/fpu: Supporting XSAVE feature 0x008: 'MPX bounds registers' [ 0.000000] x86/fpu: Supporting XSAVE feature 0x010: 'MPX CSR' [ 0.000000] x86/fpu: xstate_offset[2]: 576, xstate_sizes[2]: 256 [ 0.000000] x86/fpu: xstate_offset[3]: 832, xstate_sizes[3]: 64 [ 0.000000] x86/fpu: xstate_offset[4]: 896, xstate_sizes[4]: 64 [ 0.000000] x86/fpu: Enabled xstate features 0x1f, context size is 960 bytes, using 'compacted' format.
