[SOLVED] Slim not loading on startup

[DrunkyMcStumble]

I recently received a raspberry pi that I plan to use as an embedded car computer system, so I need to have everything on it as customised, streamlined and lightweight as possible to keep the performance nice and speedy - hence choosing Arch Linux as the OS, SLiM as the login manager and dwm as the window manager in X.

I'm completely new to Linux and to the ARM architecture, so I've just been picking things up as I've been going along. Installing everything seems to have gone OK, and I've followed the instructions in the wiki to get slim to load on startup by using: $this->bbcode_second_pass_code('', 'systemctl enable slim')

I can see it listed in the scrolling text during boot, but every time it just drops me into the usual shell login prompt rather than taking me into slim. It's not throwing up an error that I can see during boot, so if something's going wrong behind the scenes then it must be logging it to a file that I can't find. Any ideas?

Check $this->bbcode_second_pass_code('', 'tree /etc/systemd/system/') for the service.

[DrunkyMcStumble]

Yep, it's there:
$this->bbcode_second_pass_code('', '/etc/systemd/system/
└── display-manager.service -> /usr/lib/systemd/system/slim.service')

EDIT:

OK, so after searching around I found the Slim logfile in /var/log/slim.log with the following contents:
$this->bbcode_second_pass_code('', 'slim: waiting for X server to begin accepting connections.
Giving up.
slim: unable to connect to X server')

Repeated a few times, once per login no doubt. So, it seems like it's an error with X and not slim. I tried to manually start X on its own using startx, then, to see what the problem might be and got the following error:

"No screens found" - could be something with the video driver?

This is raspberry pi, X11 is broke at the moment

Thanks, but I think I figured it out - turns out that I just hadn't installed the video drivers! I pacman'ed xf86-video-fbdev, xf86-video-vesa and mesa then rebooted and it all worked like a charm.

Are those the right drivers for the Pi? I noticed that they're just generic and wondered if there's anything more tailored (read: faster) to the Pi's GPU architecture.

[pepedog]

No accelerated X drives for the pi at the moment
