recommendations for 4k video card under Linux
by Gilles Detillieux 03 May '18

03 May '18

Hi. Does anyone on the list have experience and recommendations on how to support a 4k monitor under Linux? We want to use a single Dell 27" 4k monitor (P2715Q) with a CentOS 7 system. What would be a good choice for a PCIe x16 video card, preferably with DisplayPort output, that can support 4k@60 Hz and has good driver support under X.org - hopefully without having to resort to 3rd party pre-compiled, version-specific binary kernel modules? If we can keep the price for the card below $200-$300 that would be great. Unfortunately my Google searches this morning for this have had a pretty low signal to noise ratio. Mostly people having problems with nVidia drivers. Possibly relevant h/w info: ASUS M5A78L-Mlx+ motherboard and AMD FX-6350 CPU. Power supply has a spare 6-pin (3x2) PCI-E power connector for cards that require a dedicated power connection. Thanks for any advice. Gilles -- Gilles R.

Damian Conway, "More Instantly Better Vim" - OSCON 2013
by Gilbert E. Detillieux 03 May '18

03 May '18

This guy is undoubtedly one of the top Vim wizards out there... https://www.youtube.com/watch?v=aHm36-na4-4 Some very neat tricks, and some that make you wonder why. And wonder if all the time he spends on time-saving hacks actually saves him time! Enjoy! Gilbert -- Manitoba UNIX User Group E-mail: <gedetil(a)muug.ca> c/o Gilbert E.

Out of Disk Space
by Frank H 28 Apr '18

My main os is partitioned for 89GB which has typically been plenty in the past.Running KDE Neon stable It was out of space and locking up so I booted into another partition and ran baobab against it. It says 65 GB is the size of home but the graphic and detailed list don't show the whole picture. Only about 6GB. Any ideas? Thanks,Frank

Neat tool - lsofgraph
by Adam Thompson 01 Apr '18

01 Apr '18

(Courtesy Rob Keizer) https://github.com/zevv/lsofgraph Draws a graph of the interconnected pipes, FIFOs and IPC links between running processes on a UNIX system. Examples look really cool, I can think of places I want to use this. But it requires lua. Yes, LUA. So if you happen to have lua installed, or don't mind installing it, here's a really nifty tool! -Adam
