...e found two promising solutions: NVidia NVS 510 or 450 Matrox M-series M9138 or M9148 Both these solutions claim to have Linux support, but I was wondering if anyone had any experience with them in CentOS 6.4? And if there were any other solutions I had overlooked? Thanks, -G. -- Glenn Eychaner (geychaner at lco.cl) Telescope Systems Programmer, Las Campanas Observatory

...ot;!) Is there someplace can I find *detailed* release notes on the differences between -164 and -194 kernels to help in looking for the problem, pinning it down, and submitting a patch (and/or building my own kernel), or should I just download the SRPMS and dig in?

...d, but that is complete cheese, of course. Is there something missing from ifcfg-eth0_dhcp that is confusing the system-config-network-cmd script? Is there any documentation on this that's helpful? And is there simply a better way to do this that I've missed?

...ne check events logged (I would not have even noticed them, except that they get flagged by logwatch.) These messages always occur alone, and don't seem to have a corresponding entry in any other log file in /var/log. How can I get more info about these messages?

...l/aboutasus/OS/Linux.pdf SuperMicro has a very nice list referenced above, but none of their small form factor motherboards support dual displays AFAICT; I have found nothing useful at Intel's site.)

...o the 'Welcome to CentOS " message. Do I need to "rebless" vmlinuz or initrd or initramfs in the /boot partition if I change the drive UUID? Or should I just ignore UUID and go back to using labels in /etc/fstab (which is what I did in CentOS 5)?

...der to delete it, I have to manually revert the /etc/cups files and restart the cups printing system in system-config-services. I just don't understand printer configuration on Linux. On the Macs, it's just plug and go. Why does CentOS have to make it so confusing? -G. -- Glenn Eychaner (geychaner at lco.cl) Telescope Systems Programmer, Las Campanas Observatory

...t, but I'm not an expert X11 programmer (worse, this application uses a third party wrapper library). This is definitely new behavior on this new computer (the previous computers, also using the Nouveau driver with GeForce 7600 cards, did not seem to have this behavior). -G. -- Glenn Eychaner (geychaner at lco.cl) Telescope Systems Programmer, Las Campanas Observatory

...ingle pair. [**] I'm actually using an asyncore.dispatcher to do the bind/listen, and then tossing the accept()ed socket into an asynchat. But I actually went ahead and put a trap on socket.recv() just to be sure that I'm not swallowing the 0-length recv by accident. -G. -- Glenn Eychaner (geychaner at lco.cl) Telescope Systems Programmer, Las Campanas Observatory

...ility, and dual ethernet (or an expansion slot for a second Ethernet card). Anyone have any advice on how to attack this these days? I've been out of the hardware-purchase game on the Linux side for years, and most of my bookmarks no longer point anywhere useful, sadly. -G. -- Glenn Eychaner (geychaner at lco.cl) Telescope Systems Programmer, Las Campanas Observatory

...ay only (from the remote end to the local end) by making the remote file system read-only. But it doesn't work; it doesn't seem like rsync actually reads a config file in the user's home directory. Documentation error, or am I not understanding something?

...into the latest distribution. [Yes, I'm STILL working on the workstation configuration. We're considering putting off triple-head support to cut costs, because the dreamy NVS510 cards are expensive. It's like a morass of quicksand sometimes.] Gracias y saludos, -G. -- Glenn Eychaner (geychaner at lco.cl) Telescope Systems Programmer, Las Campanas Observatory

...1) I used VFAT rather than ext2/3/4. Do I have to use ext2/3/4? 2) Do I need to rebuild the initramfs file somewhere in the CentOS LiveCD directory? 3) Is this just a straight-up hardware incompatibility? The computer is a brand-new SuperMicro X10SAE Haswell system. Thanks, -G. -- Glenn Eychaner (geychaner at lco.cl) Telescope Systems Programmer, Las Campanas Observatory

I have been trying to get to the CentOS LiveCD site at projects.centos.org the last couple of days, but have been unable to reach it. Is it down, and is there any info on when it might be back up? Thanks, -G. -- Glenn Eychaner (geychaner at lco.cl) Telescope Systems Programmer, Las Campanas Observatory

...vents such as this? Just curious... Well, projects.centos.org was up briefly over the weekend, but appears (from my end) to be down again, same symptoms; HTTP connections just hang. Next time I'll download the LiveCD instructions I'm looking for to a static file! -G. -- Glenn Eychaner (geychaner at lco.cl) Telescope Systems Programmer, Las Campanas Observatory

...that the actual UUIDs weren't important enough to me to matter, since I seldom boot with more than one workstation's drive connected at a time. I will probably go back to labels, since I can change those (apparently) without rendering the system unbootable.
