Confirmed. Was just confused with the many mouse entries in the xinfo list. For me entry 13 on my sony vaio laptop solved it. Notably, I have a usb mouse and a builtin touch pad "mouse". Just in case the bug has something to do with a possible conflict. murat ~ $ xinput --list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Macintosh mouse button emulation id=14 [slave pointer (2)] ⎜ ↳ Microsoft Microsoft IntelliMouse® Optical id=10 [slave pointer (2)] ⎜ ↳ AlpsPS/2 ALPS GlidePoint id=13 [slave pointer (2)] ⎜ ↳ PS/2 Mouse id=12 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Sony Vaio Keys id=8 [slave keyboard (3)] ↳ Power Button id=9 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)] murat ~ $ xinput set-int-prop 13 "Device Enabled" 8 0 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/637208 Title: Left mouse button stop working after the first keyboard layout switch -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
