[gentoo-user] Nouveau KMS Xorg-setup with multiple screens
Hello I have problems. I'm migrating from nvidia proprietary driver to nouveau driver because I wan't utilize KMS. The server is connected to two separate displays in separate rooms. The first display is showing tv programs and mostly runs @50Hz frame rate. The second is displaying movies and hence runs at 23.97Hz. The programs sync to VBLANK! Nobody can stand the tearing of video without it! With nvidia and UMD I had two screens and everything worked perfectly. So with this setup it's necessary to have two screens, right? Is it possible to have 2 screens with KMS and nouveau driver? -- Matti

I paid $2 each, including delivery, for a couple of rtl8192cu / RTL8188CUS wifi dongles a year ago. I actually bought them from different suppliers on eBay and, although they looked identical, they contained different RTL chipsets. As I recollect, one worked perfectly one was flakey or worked not at all, but I was running them on an old PPC iMac and assumed that was the cause. I did a fair bit of debugging, intending to post to the Linux wifi driver developers list, before losing interest. I kinda figured at such cheap prices I could, in future, afford to buy 2 or 3 wifi cards from 2 to 4 different suppliers (so $8 - $24 total) and I'd be likely to find at least one batch that works perfectly. Everyone complains when they get a cheap shitty wifi card that doesn't work, but there is probably an element of confirmation bias to this - we forget about all the cheap shitty wifi adaptors that just work perfectly. Are the name brands really that much more reliable? I originally read your comment as 10$ NICs just don't work like 40$ ones - realising that you wrote $400 is obviously a different matter. Reliability easily justifies $400 for the datacentre, but not for most home users. Stroller.

There are a couple of schools of thought there. One that differs from what you suggested is that root isn't really a pure role - it is a uid you can log in as (which mostly makes the actions you take as root anonymous in a multi-admin environment). If you're into role-based access control then you really don't want people just switching to root all the time - you want to define roles and their specific requirements, and then assign those roles to users. Sudo is a simple tool for doing this, but stuff like consolekit/logind/policykit and so on are about giving more granular access to users. Likewise posix capabilities are all about making what traditionally is root much more granular. But, yes, the simple answer is to just log in as root to power off the system. That will almost certainly work for at least the next 20 years. Everything else is just added capabilities. -- Rich

[gentoo-user] systemd: incorrect behavior when doing poweroff/reboot
I'd be 100% sure this is a systemd bug except that the problem is so obvious and (I think) so common that I can't believe I'm the only systemd user seeing it: I routinely share /usr/portage over NFS between several gentoo boxes on my wireless network. When I poweroff or reboot the NFS client machines, systemd tears down the wireless connection *before* it unmounts the /usr/portage share, and so the umount command hangs and the machine won't shut down. I'd think people that hang out in this list must do the same thing, surely? No one else here running into this silly problem?
Re: [gentoo-user] How to poweroff the system from user?

Supposedly, the only difference between poweroff and reboot is that the former turns off the machine and reboot does a reset.

I was using genkernel, but it was whining about not supporting systemd, so I tried dracut for the first time. However, the initramfs created by genkernel has the same issue. I didn't do any special configuation of dracut, I read that just running it can usually create a initramfs without any additional configuration.
