Re: how would you troubleshoot stuttering video? (Lenovo Thinkpad)
Good question! Just tried a regular pop song MP3 and got the same stuttering. Here's the mplayer output: === Requested audio codec family [mpg123] (afm=mpg123) not available.

how would you troubleshoot stuttering video? (Lenovo Thinkpad)
Lenovo ThinkPad T440s : just a couple years old. Triple-booting Arch Linux and Windows too, it's plenty fast to watch even huge HD 1080p movies. But on a new stock OpenBSD (dmesg below) it does that stuttering thing with all video, even the tiniest little YouTube or low-resolution mp4 file, even if only 3 seconds long: "ev.. er...y th... ing... stut... ters... a... few... times... per... sec... ond...", whether using mplayer or browser or any other method I've tried. I saw http://www.openbsd.org/faq/faq13.html#audioserver and tried the `rcctl set sndiod flags -b2400` advice with various frames values, huge and small, but it had no effect. Any pointers for what you'd look at, if it were you, to troubleshoot this? I'm happy to do the work, but sorry I don't know where to start.

Trying to get Wacom CTL-490 to work
I'm trying to get my new Wacom tablet working with X11 in -current.

However, it did not change anything. Does anybody know how to get X working with the uhid device? Or is that not the suggested method? Based on my findings that uhid6 is for pen movement, might ums attach to the wrong device? Thanks for any help. Frank

xlock permission problem
Hello, world! I'm having an issue with xlock being unable to unlock a locked session. I'm running a CURRENT version of OpenBSD on amd64 architecture. I can lock my X session with xlock just fine, but when I enter my password the unlock, xlock says the password is invalid. However, the password I've entered (several times) is 100% correct. Authlog provides the following hints: == xlock[82700]: Start: myusername, myusername, :0 xlock[82700]: staff: getting class information: Permission denied xlock[82700]: daemon: getting classinformation: Permission denied xlock[82700]: xlock: failed unlock attempt on user myusername xlock[82700]: xlock: xio_error xlock[82700]: Stop: myusername, myusername, :0, 6m 5s == I've googled thoroughly, checked the permissions of /etc/group etc, but have not found either a solution nor any hints on how to further diagnose the problem. Any ideas, anyone? - Jyri

This is a bug introduced by not execing dc anymore, but calling the
dc code as a function.
In that case getopt is called a second time for a new set of
parameters and it has to be reinitialized,
The code below should fix it. Recompile both dc and bc after patching.

long name functions in bc
Hi, I'm new on bc, I'm writing a library with some math functions I intend to use on calculations. I would like to use long names for variables and functions on my library but also use functions from the main math library, which I do by calling bc with '-l' flag. But once I start bc with '-l' I can't use any long name, why? Is there a way to change this behaviour? Why it works like this? Regards, Henrique N. Lengler
