Can't get sound to work and kernel to load #130

Closed SimionKreimer closed 8 years ago

SimionKreimer commented 8 years ago

Hi all, I'm probably missing something obvious but could really use the help. I reinstalled Archlinux (Antergos) after briefly switching to ChromeOS to update the SDD firmware (2.3 now, WOOT). The first thing I did was to install linux-samus4 through yaourt. I've reset the system several times and even ran the grub-mkconfig -o /boot/grub/grub.cfg command, but whenever i run uname -r it returns 4.4.5-1-ARCH. Probably related to this, I can't get the sound to work. I made the .conf file and copied all of the firmware files as the step-by-step instructions directed, but the brw device doesn't show up when I run aplay -l. I think I ran into a similar situation before, but can't recall how I got out. Please, help.

Best, Simion

Definitely looks like the kernel wasn't installed properly or maybe it was but it's not the one used to boot the machine. You should see linux-samus4 in grub and select that - do you see multiple entries in grub?

SimionKreimer commented 8 years ago

It seems like it was installed properly, I can see the image in the boot partition, and there were no errors during installation. When I boot up the computer, Ctrl+L, esc, and then select the SDD to boot from, I get a message like welcome to Grub and there is some stuff going on in the upper edge of the screen, then a few seconds later archlinux starts, I don't get an option to select the kernel.

It's because of graphics problems, I recommend checking out the example grub configuration here 0. Specifically, the setting GRUB_GFXMODE. Edit your /etc/defaultgrub file to match. Then re-run

grub-mkconfig -o /boot/grub/grub.cfg

Or however you are updating your grub, but that would be what is expected. You should then be able to reboot and see the grub menu.

@genkimarshall that's exactly what I was thinking.

This seems to be a common issue, so I've created a wiki page to address it.

Agreed this will be a helpful link!

SimionKreimer commented 8 years ago

Thank you all very much! Correcting the GRUB_GFXMODE as shown on @ehegnes wiki page totally fixed the grub and I was able to boot with the linux-samus kernel. The question I have now is if it makes sense to keep the other kernels since I'm using this one?

raphael commented 8 years ago

I would recommend keeping at least one other kernel. It doesn't take a lot of space and you never know :)

Closing this issue for now, open new ones if you have more question!
