Dell XPS fans
by InvalidPath 02 May '17

02 May '17

I believe the latest kernel update has messed with the fans on my XPS 9550, their doing the whole spin out of control thing. I have not verified this though, too busy with work stuff to reboot and start over.. yet. But I wanted to toss this out there in the off chance another XPS user has noticed something afoot with their fans. I'll bounce into an older kernel tonight and report back. Thankes! Ben

problem mounting btrfs 1 raid on boot
by joakim＠verona.se 30 Apr '17

30 Apr '17

Hello, I have a 2 disk btrfs 1 raid which I want to mount from a fedora installation on a separate ssd. This went fine for a while, until my fedora ssd died. Then I made a new fedora on a new disk. Now the btrfs raid wont mount during the boot process, but it will mount later, if I remove the btrfs raid from fstab, and mount it by hand when the machine has booted. The only difference between the first fedora install that broke, and the second one that I can think of, is that the first one used btrfs for filesystem, and the second one ext4. So I'm suspecting that the btrfs filesystem doesnt get properly loaded or something in the second case. (I just forgot to make the 2nd install use btrfs for the root partition) Is there something I can do about this? -- Joakim Verona joakim(a)verona.se +46705459454

setting time in QEMU image
by Robert Moskowitz 30 Apr '17

30 Apr '17

I have a F21 QEMU image. Use it for a number of things and not too interested in updating it. I like gthumb from back then. They have ruined a nice simple image viewer. Anyway, the issue is system time when I resume the image. The image was paused, as I have learned that if I suspend the system without pausing this QEMU F21 image, said image runs at 100% cpu and will not respond unless I kill it. Pausing it avoids this most of the time. When I reenter the image, the clock is off and it rarely resets. So far I have used system-config-time to kick off ntpdate, or whatever it is using. This is a time consuming process and it locks the system, requiring me to reenter my password (which I had to do for system-config-time). Is there some cli that I can easily use to reset the time of the image. Note that the main image, F24 always has the right time. thanks

by Joachim Backes 28 Apr '17

Hi all, Alledgely, since TB 38 lightning is full part of thunderbird. For the moment, I'm running TB 52 on F25. Going to the TB addons, seeing that an lightning addon is installed.

Problem with my home network
by Jon Ingason 25 Apr '17

25 Apr '17

Hi, I got a very strange network problem. My home network is one router (ASUS RT-N66U) (R), two Fedora machines (A F24 and B F25) connected to the switch ports on the route. I hav also a laptop, Windows 10 (C), HP ENVY AIO (P), and couple Android devices (mobile phones, tablets etc), all connected via WiFi to the router. I was installing the printer (P) on B with HP Device Manager (HPDM) and that went well. Then I started HPMD on A and the printer icon showed up in HPMD, but the printer and scanner didn't show up. Refresh didn't helped either. The I removed the printer and tried to install it again. Got message "HPLIP cannot detect printers in your network." I then pinged P from A but no response from the printer. Then I locked at the HPMD on B and every thin was OK. I could refresh the printer and both printer and scanner was there. I pinged P from B and C with success, but not from A. But I could ping B, D and R from A with success. I used Wireshark on A and B to see what is happening, but it just confirmed that P didn't respond to A, responded to B. Question is what can be the problem here. -- Regards Jon Ingason

For printing, HP tends to use TCP port 9100 for > their "JetDirect" protocol, but also can use "ipp" (TCP/UDP port 631). I can't see why the firewall should suddenly start blocking a specific address, that is the printers IP-address. Besides A can ping all devices that B can except the printer. In A's firewall, there is no rule that is specific for the printer IP-address. I have been using this printer/scanner for a over two years from machine A without a problem. I would appreciate more tips. > ---------------------------------------------------------------------- > - Rick Stevens, Systems Engineer, AllDigital ricks(a)alldigital.com - > - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - > - - > - Grabel's Law: 2 is not equal to 3--not even for large values of 2. - > ---------------------------------------------------------------------- > -- Regards Jon Ingason
