If the above message suddenly comes up in your screen after CUDA driver installation in RedHat/CentOS/Fedora OS, don’t be panic. This is happened because of xorg-x11-drv-nvidia-gl package, which is part of cuda-drivers dependencies. I got this experience in my laptop that has Intel + NVIDIA GPUs. I guess it’s because the Intel GPU is the primary GPU in my laptop, and for RedHat/CentOS/Fedora there’s no a kind of official Optimus technology, like in Windows.

got another headached error while compiling c++ in Maverick OSX (10.9)
Undefined symbols for architecture x86_64:

solution:
add -stdlib=libstdc++ -lstdc++ as compiler flags
– remove .lock file in workspace’s metadata folder.
rm {YourWorkspaceDir}/.metadata/.lock
– find out the RECENT_WORKSPACES attribute
cd ~/.eclipse
grep -r "RECENT_WORKSPACES" *
– once you got the file where the RECENT_WORKSPACES attribute exists, edit that file by removing the RECENT_WORKSPACES line.
