[FAILED] - VGA2USB installation in ArchLinux. How do you install it?

I have VGA2USB frame grabber device. Connected to my Archlinux. I want to use it and install it but cant make it installed. Help!! I have tried with latest the greatest kernel and then i switched to kernel26-lts both same, so please see as below my steps:

Part 1) How do i install kernel26-lts?

1. pacman -Syu kernel26-lts kernel26-lts-headers

2. vim /boot/grub/menu.lst

# (0) Arch Linux
title  Arch Linux
root   (hd0,0)
#kernel /vmlinuz-linux root=/dev/disk/by-uuid/15bd099c-22aa-4fa9-998e-964f5e3fedd8 ro vga=773 quiet splash
#initrd /initramfs-linux.img
kernel /vmlinuz26-lts root=/dev/disk/by-uuid/15bd099c-22aa-4fa9-998e-964f5e3fedd8 ro vga=773 quiet
initrd /kernel26-lts.img

3. mkinitcpio -p kernel26-lts

OK


Part 2) How do i now install VGA2USB?

1. Downloaded driver from: http://www.epiphan.com/downloads/linux/
name: vga2usb-3.26.0.27-ubuntu-3.0.0-12-server_X86_64.tbz

2. Tried with kernel26-lts with no luck + same issue with latest kernel too

Re: [FAILED] - VGA2USB installation in ArchLinux. How do you install it?

g'day!

Upfront: Neither have i tried using the lts-kernel nor do I own such a gadget so can't fully reproduce your case.

I used this generic driver package with the stock linux-3.0-ARCH-kernel (3.0.7-1 as of writing).

Untaring (and spraying the files all over the place 'cause there was no subdirectory), 'cd'ing into it and running 'make' yields:

[alex@opteron]$ make
make -C /lib/modules/3.0-ARCH/build SUBDIRS=/home/alex/build/vga2usb modules
make[1]: Entering directory `/usr/src/linux-3.0-ARCH'
  CC [M]  /home/alex/build/vga2usb/drvwrapper.o
  CC [M]  /home/alex/build/vga2usb/drvwrapper_lib.o
  LD [M]  /home/alex/build/vga2usb/vga2usb.o
  Building modules, stage 2.
  MODPOST 1 modules

  CC      /home/alex/build/vga2usb/vga2usb.mod.o
  LD [M]  /home/alex/build/vga2usb/vga2usb.ko

The module compiles but...

[alex@opteron]$ sudo modprobe vga2usb
FATAL: Error inserting vga2usb (/lib/modules/3.0-ARCH/kernel/drivers/usb/image/vga2usb.ko):
Unknown symbol in module, or unknown parameter (see dmesg)

... it doesn't load.

A quick glance at google and...

[alex@opteron] $ zcat /proc/config.gz | grep PARAVIRT_SPINLOCK
# CONFIG_PARAVIRT_SPINLOCKS is not set

... reveals that the stock arch kernel comes without pv-spinlocks compiled in, surprise!

Recompiling the kernel with CONFIG_PARAVIRT_SPINLOCKS=y let's the module compile cleanly and modprobeing works without flaw, too.

This is no proof that the device will work but if you can reproduce it you're halfway there.
Make sure to look at 'modinfo vga2usb' because you might have to adjust the parameters for your specific model.

No bloody idea why the driver needs this at all and I don't know if this option has any side effects setting your cat on fire, so you're on your own.
Of course your're free to file a bug-report/feature-request on the bugtracker if you feel the need for it but next time before buying new bling you should take a look at what the linux support of the respective manufacturer looks like for your favourite distro. smile

Re: [FAILED] - VGA2USB installation in ArchLinux. How do you install it?

IamTrying, please enclose your listings in [ code ] tags. This will make them better readable and show them in scrollable windows. For more info on our BBCode tags just follow the "BBCode" link below the edit window.

(I took the time to include those tags in your first post. Please do so yourself in future.)

To know or not to know ...
... the questions remain forever.

Namarrgon - off-topic advice: zgrep instead of zcat  | grep . smile
