2013-10-03 21:30:47 -0600 answered a question libGL error: failed to load driver: swrast

Things to check:

1) Is your braid executable 32-bit or 64-bit?

2) Sounds like you installed the NVIDIA proprietary driver. Was it from a repository, and if so, which packages did you install? If the executable is 32-bit and you're running a 64-bit system, be sure to also install xorg-x11-drv-nvidia-libs.i686.

3) What's the output of rpm -qa | grep -i nvidia?

4) Does running cat /etc/ld.so.conf.d/nvidia-lib64.conf output /usr/lib64/nvidia and cat /etc/ld.so.conf.d/nvidia-lib.conf output /usr/lib/nvidia?

Have you tried reinstalling, e.g., sudo yum reinstall xorg-x11-drv-nvidia-libs.{x86_64,i686}?

To talk to the outside world you should have a NAT or bridge adapter as one enabled connection in VBox. To enable the shared folders feature you need a host-only adapter. If a physical network cable is disconnected, you won't be able to do the former. What would you like to be able to do but can't?

2011-12-25 09:42:05 -0600 answered a question How to install the latest version of the Faenza icon set?

You could probably download the newest set yourself and extract it to

~/.icons/faenza-latest

Then run gnome-tweak-tool and select it. In case there's a name conflict you could yum remove the existing one.

BTW, installing the vpnc-consoleuser package allows running vpnc{,-disconnect} without sudo/su.

2011-12-23 19:03:33 -0600 answered a question emacs running slow on Fedora 16 and nvidia

I had the same problem, though it affected emacs -nw as well (didn't try emacs-nox). Also, using nouveau not the blob. Anyway, that turned out to be orthogonal to the actual issue in my case. For a possible solution, skip to the end. I did:

ltrace emacs

and stopped it at when Emacs "hung" to see what library calls were being made. The last chunk of relevant output was:

access("/usr/share/emacs/23.3/etc/charse"..., 0) = 0
gethostname("MYHOSTNAME", 255)                    = 0
index("MYHOSTNAME", '.')                          = NULL
getaddrinfo("MYHOSTNAME", NULL, 0x7fffab63a9d0, 0x7fffab63aa00 <unfinished ...>
(3, 0x3203823260, 2054, -1, 0)                   = 0x3203823260
(0, 0, 0, 3, 0x7f2f6d1f6040)                     = 0x3203823260
(3, 0x3203823260, 2054, -1, 0)                   = 0x3203823260
(0, 0, 0, 3, 0x7f2f6cff34a8)                     = 0x3203823260
(3, 0x3203823260, 2054, -1, 0)                   = 0x3203823260
(0, 0, 0, 4, 0x7f2f6cdeb718)                     = 0x3203823260

where MYHOSTNAME represents my true hostname. The last call to getaddrinfo suggested that the pause was due to a delay in resolving my hostname to an IP, or something like that. At this point, there could be a couple of solutions, some more correct than others.

What I did:

I pinged my hostname, and found that it was resolving to the IP on my local network after a similarly long pause. So, I just added my hostname to the 127.0.0.1 line in /etc/hosts. Et voilà: Emacs started up quickly. Well as quickly as your init file allows :)

To any commenters reading this: I would be interested if there's a better solution.
