I'm experiencing the same behavior after upgrading to 10.10. I have a Dell Precision M4400, and am using an external display, rotated to portrait mode using Xinerama. I can run gitk in NVIDIA's twin view or when the external monitor is disabled.
I have an NVIDIA Quadro FX 1700M. It's running the NVIDIA Driver v. 260.19.06, Server version number 11.0, server vendor version 1.9.0, NV- CONTROL version 1.24. (I'm not sure if that means anything). xxxxxxxxxxxxxxx:~$ cat /proc/driver/nvidia/cards/0 Model: Quadro FX 1700M IRQ: 16 Video BIOS: 62.94.8f.00.04 Card Type: PCI-E DMA Size: 40 bits DMA Mask: 0xffffffffff Bus Location: 0000:01.00.0 xxxxxxxxxxxxxxxxxxx:~$ cat /proc/driver/nvidia/registry EnableVia4x: 0 EnableALiAGP: 0 NvAGP: 3 ReqAGPRate: 15 EnableAGPSBA: 0 EnableAGPFW: 0 Mobile: 4294967295 ResmanDebugLevel: 4294967295 RmLogonRC: 1 ModifyDeviceFiles: 1 DeviceFileUID: 0 DeviceFileGID: 0 DeviceFileMode: 438 RemapLimit: 0 UpdateMemoryTypes: 4294967295 UseVBios: 1 RMEdgeIntrCheck: 1 UsePageAttributeTable: 4294967295 EnableMSI: 0 MapRegistersEarly: 0 RegisterForACPIEvents: 1 RegistryDwords: "" ** Attachment added: "xsession-errors" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/659473/+attachment/1705616/+files/.xsession-errors ** Attachment removed: "xsession-errors" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/659473/+attachment/1705616/+files/.xsession-errors -- gitk crashes entire X session https://bugs.launchpad.net/bugs/659473 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
