Hello! 4 days ago I became Antergos user
This is firs time for me tu using Arch
Installation went without any problems, to mention that I chose Gnome 3 desktop environment.
I am still learning Arch because its first time for me to use it.
I set-up almost everything without any problems except HDMI audio on my Radeon HD3200 graphic card that is integrated on my MB and I have problem with my dual monitor set-up,
- HDMI audio on Radeon HD3200
HDMI audio is detected on sound devices in settings but when I chose HDMI audio there is no sound.
In Ubuntu 13.10 for HDMI audio to work I have to enable HDMI audio in /etc/default/grub ading "radeon.audio=1 " , sudo update-grub and add ppa with daily opensorce radeon driver.
I folowed instructions on Arch wiki how to eneble HDMI audio and is same procedure like in Ubuntu. I added “radeon.audio=1” in /etc/default/grub and saved, sudo update-grub command dont work in Arch however I restarted my PC and HDMI audio still don’t work it is detected in sound devices but still no sound same as before editing /etc/default/grub.
Here is my /etc/default/grub:
# Preload both GPT and MBR modules so that they are not missed
# Uncomment to enable Hidden Menu, and optionally hide the timeout count
# Uncomment to use basic console
# Uncomment to disable graphical terminal
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo’
# Uncomment to allow the kernel use the same resolution used by grub
# Uncomment if you want GRUB to pass to the Linux kernel the old parameter
# format “root=/dev/xxx” instead of “root=/dev/disk/by-uuid/xxx”
# Uncomment to disable generation of recovery mode menu entries
# Uncomment and set to the desired menu colors. Used by normal and wallpaper
# modes only. Entries specified as foreground/background.
# Uncomment one of them for the gfx desired, a image background or a gfxtheme
# Uncomment to get a beep at GRUB start
#GRUB_INIT_TUNE=“480 440 1”
- My second problem is dual monitor set up.
Like I sad I have Radeon HD3200 integreted in my MB and I use D-SUB for 22" Samsung monitor and HDMI for 42 "LG 3D HD TV.
When HDMI and D-sub is connected picture is fine on login screen ( normal size, without artefact etc.) but when I log in picture is some kind magnified, Gnome Top bar is huge, windows and fonts are huge.
I checked resolution settings and it says it is correct resolution but everything is so big on bot screens, top bar windows, fonts etc.
When I disconnect HDMI and restart PC picture on Samsung monitor is normal, normal size top bar, fonts and windows and if I plugin HDMI while PC still works picture extends on LG TV and picture on both monitors are normal until reboot then picture is huge on TV and Monitor. I don’t know if this is driver bug or Gnome bug?
If someone know solution for this two problems I be grateful
