Default OpenBSD as a desktop

Hi all,

It's been two weeks now that I successfully moved my home little mail/sftp server on OpenBSD. I'm more than happy with it and I would like trying to use it as a desktop, but I have a few problem that I could not solve.

I should mention that I tried xfce4 only because this is what I've been using with linux for years, but I'm more than open to test other solutions should they solve my problems.

My laptop (lenovo R61i) has a nvidia card, unfortunately ! Moving windows is quite slow, resizing them litterally takes seconds. 'Xorg -configure' gave me this :

I either commented the corresponding "nv" or "vesa" device code blocks, the vesa is slightly better but it's still very slow, and I can't even read a video with vlc (error is no XVideo adapter found, but I can see the first frame of the video...still this might be an unrelated problem but I didn't find anything usefull on the net. I also changed the video output in vlc config to all the available options, without success)
Did I miss something or I can't expect more with this video card?

-Mounting
I could mount fat32 USB keys but not ext3/ext4 :

# /sbin/mount_ext2fs /dev/rsd0i /home/me/Desktop/moutingFolder
mount_ext2fs: /dev/rsd0i on /home/me/Desktop/moutingFolder: Block device required

-Cryptography
I have a LUKS encrypted hard drive, but from what I understand the source code is for linux only, so compiling it on openbsd won't work as far as I understand...

Well, that's about it, comments/advices appreciated !

nvidia is garbage on OpenBSD. The only reason it works so well in Linux is because the kernel devs were willing to sign NDAs, which Theo is adamantly against.

You'd be better off with a supported Intel or ATI chipset for video.

re: Mounting ext3fs/ext4fs

You cannot mount ext4fs. Usually you can mount ext3fs as ext2fs because ext3fs is ext2fs with some features like journalling tagged on. See https://en.wikipedia.org/wiki/Ext3fs

This should do it:
# mount -o ro /dev/sd0i /mnt

If it does not please post what fdisk reports: # fdisk sd0

Thx for your answers.
@rocket357
If I buy an ATI card (not the lastest/most expensive ones) can I expect to run smoothly HD videos? Or to have some sort of graphical acceleration on the desktop?

@J65nko
This worked well with ext3. What does 'ro' mean? I couldn't find it in the man page of mount or mount_ext2fs.
Also, is there a specific reason there isn't automouting?

Michael Lucas' 2nd edition of AO gives much the same info you, J65nko, except that he instructs one to use the mount_ext2fs utility to mount ext3fs. The man page for mount_ext2fs does not state explicitly to use the utility for mounting ext3fs -- if I missed it, forgive me -- but rather leaves the subject of ext3fs undisclosed, for further research. btw, ro = readonly

$ dmesg | grep ATI
vga1 at pci1 dev 0 function 0 "ATI Radeon HD 3450" rev 0x00

Works relatively well, not the fastest acceleration (far from it), but better than software rendering. Just don't xrandr a monitor sideways...that seems to make it painfully slow and borderline unstable.

# with monitor sideways...
$ glxgears
IRQ's not enabled, falling back to busy waits: 0 11
2160 frames in 5.0 seconds = 431.991 FPS
2191 frames in 5.0 seconds = 438.047 FPS

# monitor normal...
$ glxgears
IRQ's not enabled, falling back to busy waits: 0 11
3645 frames in 5.0 seconds = 728.989 FPS
3644 frames in 5.0 seconds = 728.665 FPS

Like I said, not even close to the best, but better than software rendering...

For the meaning of -o ro see the mount(8) man page
