[arch-general] [Classroom] Python for Beginners - Part 1
by fsckd 13 Jun '18

13 Jun '18

Hello, The class Python for Beginners - Part 1 will be held on Wednesday, October 04, 2017 at 16:00 UTC in the channel #archlinux-classroom on the freenode network. The class is expected to run for about 2 hours. This class will introduce you to programming with Python and how to use IPython with an editor/IDE. Commonly used built-in functions and libraries will be explained. Other topics will explored based on participant interests. The class will be screen-shared live (via YouTube), and later archived with subtitles. Questions and some discussion on IRC is expected, however the main part will be video and audio. In preparation for the class, install the Jupyter notebook. ``pacman -S jupyter`` or, in a Python 3 virtualenv, ``pip3 install jupyter``. Also check out the python-beginners git repository on Arch Classroom's GitHub[1] where you will find IPython notebooks and links to useful resources on learning Python: https://github.com/archclassroom/python-beginners pulec is an Arch Linux user since 2012, gamer and gardener.

[arch-general] offlineimap wiki page
by Jude DaShiell 30 Jan '18

30 Jan '18

I found IMAP: offlineimap is a syntax violation in my .muttrc file. I am trying to set up offlineimap to sync my gmail account though I already have mutt able to read and write my gmail though not with encryption yet. I have nmh installed and ran install-mh in my user directory. Eventually if I can get offlineimap working I'd like to get whichever version of notmuch will work best with this arrangement installed and working too. I tried this with different instructions and got as far as offlineimap -o and ran into an error since the gmail-repository ca-cert.crt file couldn't be found on my system. --

I doubt I can held get ddcutil working, but the problem is a lack of an nvidia kernel module interface with /sys/class/backlight (which can be frustrating). You do not want to use xbacklight -- which ironically does not control actual backlight (display power), but instead controls pixel darkness (the amount of black/white per-pixel). Reducing backlight does not reduce display power, it just makes the pixels darker giving the impression of reduced brightness. (this is really bad for laptop battery life where reducing the display power is important) You want xrandr. Query with `xrandr -q` and find your interface and you can then set the desired brightness with something similar to xrandr --output LVDS-0 --brightness 42 (where LVDS-0 is your monitor connections shown by --query) Modern desktops generally integrate xrandr control (if not, you can simply implement a short script that allows you to check and set the desired brightness. There were also several AUR packages (nvidia-bl, and nvidiabl or similar) that provided a /sys/class/backlight kernel module that would would work with most laptops, but I don't think they are maintained any longer. (there was an example script on the X11 wiki some time ago for doing this) That is another option. I tried using xrandr to adjust brightness, but it doesn't modify brightness on monitor. Then I stumbled upon [1] to learn that backlight can't be actually controlled with xrandr on LCD/LED monitors: --brightness brightness Multiply the gamma values on the crtc currently attached to the output to specified floating value. Useful for overly bright or overly dim outputs. However, this is a software only modification, if your hardware has support to actually change the brightness, you will probably prefer to use xbacklight. And as described in the initial question, xbacklight doesn't work with my NVIDIA card despite all the kernel parameters. However, with ddcutil I was able to set contrast and brightness at monitor hardware level so that even at low brightness levels the screen remained perfectly legible. With xrandr, modifying the brightness distorts the colors of text. The text is readable but not white anymore. I'll see if there's some other solution. Regards.

[arch-general] ddcutil not working with nvidia card
by Foxtrot Mike 23 Jan '18

Hi all, With my AMD card, I was able to set my monitor's (ViewSonic VA2249, connected via DVI) brightness and contrast from command line using: ddcutil --display 1 setvcp 12 20 Later on, I swapped AMD card with an NVIDIA one (using nvidia 387.34-20). I tried using ddcutil with this new card as well, but I got this error: ~$ sudo ddcutil detect Failure getting EDID for /dev/i2c-5: status code=DDCRC_EDID(-3016): invalid EDID No displays found ~$ I tried googling this error, but didn't find anything helpful. So I tried using xbacklight instead. It didn't give any positive results either, even when I provided different kernel paramters as discribed in [1]. No matter what I do with acpi and kernel parameters, "/sys/class/backlight/acpi_video0/brightness" doesn't give actual values. Also, 'xbacklight set' has no effect on screen brightness at all. I also tried adding `Option "RegistryDwords" "EnableBrightnessControl=1"` in "/usr/share/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf". Still keyboard brigthness keys couldn't change the brightness. Can someone help me get ddcutil working with nvidia proprietary driver? Regards.

[arch-general] Why there is no NetworkManager in ArchISO
by Junayeed Ahnaf 12 Jan '18

Hello, Why is there no NetworkManager in ArchISO? Isn't it widely accepted as the go to method of connecting to internet in Linux? Is there any reason for it not to be default? Thanks J
