Description of problem: System is Fedora 21 running within VMware Workstation 11.1.0, hosted on Windows 7 Enterprise SP1, 64-bit. Sometimes when user logs out of GNOME, the screen freezes with no mouse pointer; no interaction of any kind seems to work, but forcing a shutdown from VMware does eventually shut the machine down cleanly after a few minutes. Examining the running X server at the point of the hang shows something like this: #0 vmwgfx_pixmap_present_readback (vsaa=0xb6a650, pixmap=0xbbab80, region=0xbbabf8) at vmwgfx_saa.c:240 #1 0x00007fdb88bc9d1e in vmwgfx_download_from_hw (driver=0xb6a650, pixmap=0xbbab80, readback=0xbbabf8) at vmwgfx_saa.c:353 #2 0x00007fdb88bcb14d in vmwgfx_saa_drop_master (pScreen=<optimized out>) at vmwgfx_saa.c:1612 #3 0x00007fdb88bc3da3 in drv_leave_vt (arg=0xb01840) at vmwgfx_driver.c:1207 #4 0x00007fdb88bc42e7 in drv_close_screen (pScreen=0xb01290) at vmwgfx_driver.c:1260 #5 0x00000000004aeed7 in xf86CrtcCloseScreen (screen=0xb01290) at xf86Crtc.c:734 #6 0x00000000004cd2a8 in CursorCloseScreen (pScreen=0xb01290) at cursor.c:187 #7 0x0000000000517614 in AnimCurCloseScreen (pScreen=<optimized out>) at animcur.c:106 #8 0x0000000000518f72 in present_close_screen (screen=0xb01290) at present_screen.c:63 #9 0x000000000043d3e7 in dix_main (argc=16, argv=0x7ffd03e71648, envp=<optimized out>) at main.c:349 #10 0x000000349ca1ffe0 in __libc_start_main () from /lib64/libc.so.6 #11 0x00000000004276ee in _start () and single-stepping the server shows it is stuck in this loop: 1605 WSBMLISTFOREACH(list, &vsaa->pixmaps) { 1609 if (!vpix->hw) 1612 (void) vmwgfx_download_from_hw(&vsaa->driver, spix->pixmap, 1613 &spix->dirty_hw); 1612 (void) vmwgfx_download_from_hw(&vsaa->driver, spix->pixmap, 1614 REGION_EMPTY(draw->pScreen, &spix->dirty_hw); 1605 WSBMLISTFOREACH(list, &vsaa->pixmaps) { Forcing the vmwgfx_saa_drop_master function to return results in a successful logout. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.16.3-2.fc21.x86_64 xorg-x11-drv-vmware-13.0.2-5.20140613git82c9b0c.fc21.x86_64 How reproducible: Not every time, but logging in and out a few times usually triggers the hang.
