Re: [opensuse-factory] DisplayLink
Damian, as you can see from my output, udl is in use already, I don't
even have udlfb available... modesetting is also installed. What
should I try with xrandr?

Getting back to this one - now that I've received the actual display...

When connected

I should see the Display here, but I don't. hwinfo provides

SysFS BusID: 2-1.5:1.0
Hardware Class: unknown
Model: "DisplayLink Lenovo LT1421 wide"
Hotplug: USB
Vendor: usb 0x17e9 "DisplayLink"
Device: usb 0x03e0 "Lenovo LT1421 wide"
Revision: "1.08"
Serial ID: "6V9BZHC1"
Driver: "udl"
Driver Modules: "drm_usb"

so, should I be using the udl or fbudl driver, I don't see the fb*udl
anywhere...

Thanks!

Hi,

Anyone out there using DisplayLink? - is it "tested" in Factory?

ie, perhaps

http://support.lenovo.com/en_US/product-and-parts/detail.page?&DocID=PD015702

Thanks

It depends - there are two generations of the DisplayLink chipset, the old
USB2 chipset(s) [1] and the newer USB3 ones [2].

The DL-1x5 series works fine with the current kernel, out of the box. You
must
add the new output manually (see "xrandr --help | grep provider"), but thats
it. (Tested on 12.3 with Kernel 3.11.x)

As far as I know, the DL-3000 series does *not* work.

The LT1421 seems to be using one of the old chipsets, so it *should* work.

Regards,

Stefan
