You have been subscribed to a public bug: Move the mouse over the launcher and the EVERYTHING on the desktop disappears for a few seconds. Only the wallpaper remains. Failed immediately after the latest update (installed by me on 5 Jan 2018) and a reboot. Reboot doesn't help.
Launcher and the other desktop displays return after a 10 to 30 second pause. No disk activity is observed during recovery. "ClassicMenu Indicator" is installed and it is the only way to start an application. Executing the bug and then immediately examining all the /var/log logs showed no recorded error or incident in any log. uname -a = Linux bruce-Latitude-D630 4.10.0-42-generic #46~16.04.1-Ubuntu SMP Mon Dec 4 15:57:59 UTC 2017 i686 i686 i686 GNU/Linux Abridged hardware list from sudo lshw description: Portable Computer product: Latitude D630 vendor: Dell Inc. width: 32 bits capabilities: smbios-2.4 dmi-2.4 configuration: boot=normal chassis=portable uuid=44454C4C-6E00-1039-8032-B2C04F376831 *-core description: Motherboard vendor: Dell Inc. physical id: 0 serial: .2n927h1. . *-firmware description: BIOS vendor: Dell Inc. physical id: 0 version: A12 date: 06/20/2008 size: 64KiB capacity: 1984KiB capabilities: isa pci pcmcia pnp upgrade shadowing cdboot bootselect int13floppy720 int5printscreen int9keyboard int14serial int17printer int10video acpi usb agp smartbattery biosbootspecification netboot *-cpu description: CPU product: Intel(R) Core(TM)2 Duo CPU T7250 @ 2.00GHz vendor: Intel Corp. physical id: 400 bus info: cpu@0 version: 6.15.13 serial: 0000-06FD-0000-0000-0000-0000 slot: Microprocessor size: 2GHz capacity: 2001MHz width: 64 bits clock: 200MHz capabilities: x86-64 fpu fpu_exception wp vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx constant_tsc arch_perfmon pebs bts aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm lahf_lm tpr_shadow vnmi flexpriority dtherm ida cpufreq configuration: cores=2 enabledcores=2 id=0 threads=2 *-cache:0 description: L1 cache physical id: 700 size: 32KiB capacity: 32KiB capabilities: internal write-back data configuration: level=1 *-cache:1 description: L2 cache physical id: 701 size: 2MiB capacity: 2MiB clock: 66MHz (15.0ns) capabilities: pipeline-burst internal varies unified configuration: level=2 *-logicalcpu:0 description: Logical CPU physical id: 0.1 width: 64 bits capabilities: logical *-logicalcpu:1 description: Logical CPU physical id: 0.2 width: 64 bits capabilities: logical *-memory description: System Memory physical id: 1000 slot: System board or motherboard size: 2GiB *-bank:0 description: DIMM DDR Synchronous 667 MHz (1.5 ns) product: V916765G24QCFW-F5 vendor: ProMOS/Mosel Vitelic physical id: 0 serial: 07B02E7C slot: DIMM_A size: 1GiB width: 64 bits clock: 667MHz (1.5ns) *-bank:1 description: DIMM DDR Synchronous 667 MHz (1.5 ns) product: V916765G24QCFW-F5 vendor: ProMOS/Mosel Vitelic physical id: 1 serial: E9AE2E7D slot: DIMM_B size: 1GiB width: 64 bits clock: 667MHz (1.5ns) *-pci description: Host bridge product: Mobile PM965/GM965/GL960 Memory Controller Hub vendor: Intel Corporation physical id: 100 bus info: pci@0000:00:00.0 version: 0c width: 32 bits clock: 33MHz ** Affects: mesa (Ubuntu) Importance: Undecided Status: New ** Tags: bot-comment -- Unity launcher disappears on mouse-over launcher https://bugs.launchpad.net/bugs/1741925 You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
