[Bug 321444] [NEW] cursor with synergyc client is stuck in upper left corner
Public bug reported: Binary package hint: xserver-xorg-input-mouse After upgrading to the latest xserver-xorg-input-* packages on jaunty alpha, the synergy client mouse handling stopped working correctly. When the client is running, it properly transfers the mouse from the server to the jaunty client, but the cursor only ever appears in the upper leftmost corner of the screen on the client. Any movement of the mouse from the host server re-jumps the cursor to that corner on the client. Keyboard and mouse input generated using the client's input devices remains functional and keyboard handling through synergy appears to be working fine still also. ** Affects: xserver-xorg-input-mouse (Ubuntu) Importance: Undecided Status: New -- cursor with synergyc client is stuck in upper left corner https://bugs.launchpad.net/bugs/321444 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 321444] Re: cursor with synergyc client is stuck in upper left corner
Sorry to not include these earlier, but I believe the relevant upgrade in xserver-xorg-input-mouse occurred from 1.3.0 to 1.4.0. synergy is at version 1.3.1-5ubuntu1, but has not been changed since this machine was installed. -- cursor with synergyc client is stuck in upper left corner https://bugs.launchpad.net/bugs/321444 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This occurs for me in 12.04 with an internal application we have which starts minimized. No amount of clicking on its icon in the dock or anything else I have found has the ability to un-minimize it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/892251 Title: Applications that start minimized cannot be unminimized To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/892251/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1020210] [NEW] Race condition using ATOMIC_FASTBINS in _int_free causes crash or heap corruption
Public bug reported: We have an application which makes heavy allocation and de-allocation demands from multiple threads. We run this application continuously on many servers, and once every several CPU months or years, we were getting a crash in _int_free that did not look like vanilla heap corruption. I believe I have narrowed it down to a race condition in _int_free due to the ATOMIC_FASTBINS feature. Basically, in the lockless FASTBIN _int_free path, a chunk is pulled into a local variable with the intent to add it to the fastbins list. However, the heap consolidation/trim code can race with this, and can coalesce the entire block and/or give it back to the OS before _int_free has a chance to try and store it into the fastbins list. The problem is very challenging to reproduce in situ, but using gdb I have a recipe which demonstrates the crash 100% of the time on my 12.04 x64 system running eglibc 2.15. It relies on malloc_trim, although in our in situ data, the consolidation is triggered as a result of a normal free. malloc_trim is just easier to control. While I am not a glibc developer, I could not see any easy ways to fix the situation shy of disabling ATOMIC_FASTBINS. I am attaching the reproduction source.

What happened: A SIGSEGV after the final continue. ** Affects: eglibc (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1020210 Title: Race condition using ATOMIC_FASTBINS in _int_free causes crash or heap corruption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/1020210/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
