Re: USB mouse not working

[Bojan Nastic]

Have you tried disabling USB3 in the BIOS?
Forcing USB2.0 helped with similar problems on my Thinkpad.

Displaylink and xorg.conf

[Bojan Nastic]

Hi List,

Anyone with displaylink/udl experience who could shed some light on the 
subject? How do you go about setting up displaylink adapters/displays?

I'm trying to set up a Lenovo USB display ("udl0 at uhub1 port2 
DisplayLink Lenovo LT1421") to work alongside my laptop, but can't get 
them to work together -- it's either one working or the other, but 
never both.

If I add a following section to (otherwise non-existant) xorg.conf:

Section Device
 Identifier "Card0"
 Driver "wsudl"
 Option "Device" "/dev/ttyD0" #<--- ttyD0 first created with MAKEDEV
EndSection

then I get properly configured USB display from X, but the builtin 
display is switched off (and never even mentioned in the logs, or 
RandR). If I add the builtin to the xorg.conf (as "Card0", and move USB 
to "Card1") then X ignores wsudl driver completely and never mentions 
it in the logs, and only activates the builtin display. There are no 
errors or warnings mentioned.

I must be missing something simple -- I found a couple of emails from a 
while ago on this list with similar issues, but the solution that used 
to work in 5.2/5.3 (put both cards/screens in xorg.conf, like I tried) 
doesn't appear to work here.

(Also, what would it take to make it hot-pluggable, so I don't have to 
fiddle with xorg.conf?)

Thanks
Bojan

Can confirm - that D-Link modem is the best way to go (at least in our 
neck of the woods). Very cheap and reliable. I have it running as a 
PPPoE bridge into an Alix 
router with OpenBSD. The whole rig has been up for more than a year, 
zero issues.

EHCI/XHCI and USB sound on Thinkpads

[Bojan Nastic]

Hi misc@

I'm seeing inconsistent USB behaviour between USB2 and USB3 on different
Thinkpads running -current with Cambridge Audio DACMagic
XS USB audio card (class 2 audio device).
This card otherwise works perfectly fine over USB3 on a Mac laptop.

- When plugged into a USB2 port on Thinkpad X220 the card is recognised
properly:

uaudio0 at uhub4 port 2 configuration 1 interface 0 CA CA DacMagicXS 1.0
rev 1.00/6.04 addr 3
uaudio: audio rev 1.00 1 mixer controls
audio1 at uaudio0

- But when plugged into a USB3 port on X220 (via a usb3 express-card):

uhub1: device problem, disabling port 4

- Same error as above on any of the USB3 port on Thinkpad X1 Carbon.
There are no other errors that I can see.

Any idea where to start debugging this? I'd really like to be able to use
this on my X1 Carbon (assumming this is supported?)

For reference, dmesg for both laptops:

- USB on Thinkpad x220 (builtin usb2, expresscard usb3):

ehci0 at pci0 dev 26 function 0 Intel 6 Series USB rev 0x04: apic 2 int 16

Re: Thinkpad X1 Carbon Suspend issue

[Bojan Nastic]

OK, in case someone finds this useful - got the Lid working as well.
Disabling everything suspicious and not needed in the BIOS seems to have
done the job. (esp. disabling the Intel Rapid Start, as it seems to
interfere with sleep states. But this could be just a coincidence).

X1 Carbon 2nd Gen is now 99% operational (harmless Intel drm errors
remaining).

 What doesn't quite work:

 - HD5000 driver is spewing errors on sleep/wake,
 so waking from within X will show console errors

Thinkpad X1 Carbon Suspend issue

[Bojan Nastic]

Hello misc,

Anyone having much luck with 5.7 or -current on Thinkpad X1 Carbon
2nd gen (Haswell chip)?

Everything seems to be working fine, except for waking from suspend.
Suspend works fine, either via 'zzz' or closing the lid, but waking
it up doesn't work -- hardware seems unresponsive, the sleep light stays on
regardless of what I do to it (pressing buttons, opening the lid...)

Tried 5.7 release, then upgraded to -current (as of 23.05.), still the same
problems. (Haven't cheked 5.6 for regressions, though).

Dmesg given below. Thinkpad runs a full disk encryption on root, if that
matters.
There are some Intel HD errors reported, which I've neer seen before:
error: [drm:pid0:i915_write32] *ERROR* Unknown unclaimed register before
writing to 10
error: [drm:pid0:intel_dp_set_link_train] *ERROR* Timed out waiting for DP
idle patterns
error: [drm:pid0:i915_write32] *ERROR* Unknown unclaimed register before
writing to 64040

Any ideas? How can I debug this further?

Cheers,
Bojan

Re: web development on OpenBSD

[Bojan Nastic]

eBay used to use C++. There was a .pdf some time ago where they  
described some of their C++ stuff (and compiler errors like too many  
class methods, good ol' code generators...)
They've since moved to Java, but I don't remember if it's a 100% Java  
shop now.


As for Amazon, look at their Web Services for some ideas. Also, Steve  
Yegge's old blog (don't have the url at hand) has many pointers.


So, yes, go for Python wherever you can. Ruby is in very bad shape  
internally (language can be as pretty as they want, but VM is what I  
care about the most).
PHP, well... you should use it ONLY if you know *exactly* what you're  
doing, otherwise it's worse than C++ when it comes to shoot yourself  
in the foot.

There are some very nice alternatives, like seaside/Smalltalk.
