Dear all,
I recently installed Arch on my notebook and I cannot complain at all. The notebook is working almost compleatly out of the box. However, a list of few things are not working as wanted. I'll address them separately in other threads though. Here, I have the following problem:
I'm using a Samsung 530U4E-S02. This notebook has two GPUs. A Radeon HD8750M and the integrated Intel GPU HD 4000 (from an i5-3337U). I installed budgie-desktop with gnome and I'm running GDM as Display Manager. Also I installed xf86-video-amdgpu as well as xf86-video-intel.
A feature I had on windows was wakeup from Standby when opening the lid of the notebook after I closed it before. This is not working on Arch though. I tried to figure out what the problem is. I read of people wanting to disable this feature, which is possible with 'echo LID > /proc/acpi/wakeup'. When examining the content of this 'file', the output is:
It seems like the LID is not detected at all. Do I have to compile a custom kernel for this? My research one the Internet did not yield a useful information. Maybe somebody of you has an idea.
Looking forward to your answers!

Best wishes,
fwillo

I'm running Arch on a Samsung NC20 laptop/netbook with the openchrome driver. I almost always use this laptop hooked up to an external monitor. When I first installed Arch, and for a few weeks thereafter, the laptop's own screen (LVDS-1) did not work: it would cycle between red, green and grey blocks of colour and then go black. I found the following post
that seemed to describe the problem and followed the solution given there: passing
to the kernel at boot. I've added this to the 'APPEND' line in /boot/syslinux/syslinux.cfg and the laptop's screen is now working... after a fashion.
The problem is that it now flickers, with horizontal lines, so violently that I sometimes cannot read it at all. This means that I cannot use the laptop without an external monitor. The external monitor that I use does not flicker at all while this goes on, however. It is rock solid, even though it is displaying the same thing as the laptop's screen. (I've not yet set up multihead.) The flickering begins as soon as the boot menu appears, before I've started X11.
After looking around at previous threads, I've tried disabling KMS by passing

to the kernel, but this did not work. Nor did passing
to the kernel.
Any ideas, anyone, on what to do next?
