How to remove second GDM/login screen
by Wolfgang Pfeiffer 05 Apr '18

05 Apr '18

Hi all Running an X session via GDM and awesome wm on one tty. And on another tty there's another GDM login screen waiting ... I'd like to get rid of that second and useless GDM login screen. Permanently. Is it doable? Or do I need to switch to another display manager? Thanks a lot in anticipation. -- Wolfgang Pfeiffer

Thunderbird Issue Possibly Related to System Update
by Stephen Morris 04 Apr '18

04 Apr '18

Hi, I have an issue with Thunderbird that may or may not be system related. This issue surfaced after a system update a few updates back. Whenever I start Thunderbird now it always starts unmaximised even though on last shutdown it was maximised, and when I reply to a mail or compose a mail that starts unmaximised as well. Until the system update these components of Thunderbird always started maximised as required. I'm on version 61.0a1 of Thunderbird. Is anyone else seeing similar issues? regards, Steve

Dnfdragora Issues
by Stephen Morris 02 Apr '18

02 Apr '18

Hi, I have encountered some issues with dnfdragora, one of which is fairly serious for me. If I use the search function to get a list of specific packages, it displays the details for the first package which is fine. If I then click on another package it does not show the details for the clicked package, I have to uncheck/recheck if it is installed or check/uncheck if it is not installed, to see the details. Having done this once clicking on packages in the search results displays the details correctly for the rest of the display of the search results. If I issue another search query the issue repeats itself. This issue occurs every time I use dnfdragora. The second issue which for me is a bit more serious, is that when I look at the steam related packages from the negativo17 repository, and attempt to look at the changelog to get the contact details for the maintainer, dnfdragora tells me the change details are missing, but if I do the same thing with yumex it shows the changelog details, so the changelog is actually there. Has anyone else encountered this issues and have a solution? regards, Steve

What is the universal (world wide) understanding behind degaussing harddisks?
by Turritopsis Dohrnii Teo En Ming 02 Apr '18

02 Apr '18

Good evening from Singapore! The foremost question which I want to ask is, what is the universal (world wide) understanding behind degaussing hard drives? I work for No Secrets Agency (NSA) Pte Ltd (fictitious company name used). My sales manager Edward Joseph Snowden (fictitious individual name used) had *promised* our customer Leave Me in the Lurch (S) Pte Ltd (fictitious company name used) that we would "DEGAUSS" their hard disks after the PC replacement and data migration exercise for 15 trillion PCs (fictitious number used). PC = Personal Computer, which includes desktops and laptops Last Friday, I had already reflected to my sales manager Edward Snowden that since we are definitely NOT going to wipe our customer's data by using strong and powerful magnets (physical means), should I send an email to the IT Administrator of our customer Lady Gaga (fictitious individual name used) asking her which data sanitization method (by software means) I should use? My sales manager Edward Snowden had quickly deflected my concerns (that is, wanting to send an email to our customer Lady Gaga asking her which data sanitization method I should use). I had brought up to the sales manager Edward Snowden a number of data wiping methods by software means last Friday. (1) Very very simple 1-pass data wiping, quickest a. Using "sudo dd if=/dev/zero of=/dev/sda", overwriting harddisks from beginning to end with zeroes, where /dev/sda refers to the 500 GB harddisk, not /dev/loop0 and not /dev/sdb which refers to the bootable live operating system on thumb drive b. Using "sudo dd if=/dev/urandom of=/dev/sda", overwriting harddisks from beginning to end with random data, where /dev/sda refers to the 500 GB harddisk, not /dev/loop0 and not /dev/sdb which refers to the bootable live operating system on thumb drive Any bootable Live CD/DVD/flash media could do it. (2) 3-pass U.S. Government/Department of Defense (DoD) standard (DoD 5220.22-M) Certified commercial software required (3) 7-pass U.S. Government/Department of Defense (DoD) standard (DoD 5220.22-M) Certified commercial software required (4) 35-pass Gutmann method, slowest Certified commercial software required All these was last Friday. In the midst of our argument over the cellular network "just now", my sales manager Edward Snowden tried to cover up himself by suddenly and unexpectedly making an excuse that he had told me last Friday I was supposed to wipe user data only, not the operating system! If he had wanted me to wipe user data and retain/keep the Windows operating system, he should simply have told me to Reset the PC (for Windows 10 only) or use a =secure File Shredder=! For Windows 7, you can still wipe user data and preserve the operating system by using the Recovery Partition. On Lenovo desktops, press and hold F11 when Windows 7 is starting and reset to factory defaults. I had advised my sales manager Edward Snowden not to use BIG WORDS like "degaussing the harddisk" and market to the customer using these big words. Any person who sees the word "degauss" would have understood it to mean sanitize *ALL* data on the harddisk straight away and without question. Please refer to Figure 1. Exhibit A below for the "degaussing" instructions communicated to me by my sales manager Edward Snowden. Please click the link below. URI: https://i.imgur.com/bGOMyVs.png Please advise. Thank you very much. Regards, Mr. Turritopsis Dohrnii Teo En Ming Systems and Network Engineer Republic of Singapore 2nd April 2018 Monday 9:35 PM Singapore Time GMT+8

USB issues in fedora-27 ("can't get device qualifier: Resource temporarily unavailable") not happening when booted into CentOS-6.2, same hardware
by Tom Hodder 01 Apr '18

01 Apr '18

Hi All, I've been having a bunch of trouble with the USB ports on my desktop, in particular the webcam doesn't work and there are lots of errors in the output <https://paste.fedoraproject.org/paste/qYxQ2rH-tlsE8pJqWz442w> of *"lsusb -v"* when I try to debug. (I get the "can't get device qualifier: Resource temporarily unavailable" errors, whether the webcam is plugged in or not, which seems to eliminate the webcam itself as the source of the problem) On the positive side, a usb keyboard, mouse and USB sticks seem to work ok. The hardware is a Supermicro SuperWorkstation 7037A-i <https://www.supermicro.com/products/system/tower/7037/sys-7037a-i.cfm>, with an X9dai motherboard <https://www.supermicro.com/products/motherboard/xeon/c600/x9dai.cfm>. I assumed the problem was hardware related and raised a ticket with supermicro. They asked me to test the machine using a supported OS, and the nearest to fedora-27 was CentOS 6.2 (compatibility matrix <https://www.supermicro.com/support/resources/OS/C602_listing2.cfm>). So today I booted into Centos-6.2. To my surprise there were no errors in the "lsusb -v" output <https://paste.fedoraproject.org/paste/yVFlRYGi9m4ZCt9PZPF3Gg>, no errors in dmesg or syslog, and the webcam worked fine. This seems to suggest it's not a hardware problem, but some difference in the drivers. I am pretty sure the usb/webcam used to work, but that's going back a few versions of fedora, and probably 3/4 years. Any ideas on what might be causing this? Many Thanks, Tom Various debugging output; *Fedora-27* lsusb -v https://paste.fedoraproject.org/paste/qYxQ2rH-tlsE8pJqWz442w dmidecode https://paste.fedoraproject.org/paste/gW9D10O0fy6-p58I-YgJOQ dmesg https://paste.fedoraproject.org/paste/hnVj1hyjDpyYtiInxPGZ3Q lsmod https://paste.fedoraproject.org/paste/bZTVW-7P8mD19cLO6nogww *CentOS-6.2* lsusb -v https://paste.fedoraproject.org/paste/yVFlRYGi9m4ZCt9PZPF3Gg dmesg output https://paste.fedoraproject.org/paste/TTyqm9zDrf1m4kID9rl09Q dmidecode https://paste.fedoraproject.org/paste/FfafH1-KdNzy5IA17oD9mg lsmod https://paste.fedoraproject.org/paste/~orePKeYsJRlBRmP1P2vvw Plugging in the webcam produces this; Mar 30 02:19:24 pc03.config kernel: usb 2-1.7: new high-speed USB device number 8 using ehci-pci Mar 30 02:19:25 pc03.config kernel: usb 2-1.7: New USB device found, idVendor=045e, idProduct=0294 Mar 30 02:19:25 pc03.config kernel: usb 2-1.7: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Mar 30 02:19:25 pc03.config kernel: usb 2-1.7: Product: Video Camera Mar 30 02:19:25 pc03.config kernel: usb 2-1.7: Manufacturer: Microsoft Mar 30 02:19:25 pc03.config kernel: usb 2-1.7: SerialNumber: 000F330333475838 Mar 30 02:19:25 pc03.config kernel: uvcvideo: Found UVC 1.00 device Video Camera (045e:0294) Mar 30 02:19:26 pc03.config kernel: uvcvideo 2-1.7:1.0: Entity type for entity Extension 3 was not initialized!

easiest way to encrypt existing home dir?
by Neal Becker 01 Apr '18

01 Apr '18

I'm running f27 with everything on one drive. /home is 1 btrfs subvolume and / is another btrfs subvolume. I want to move my /home to encryption. One possibility seems to be to use ecryptfs. I tried creating a test user, and the following: https://cloud-ninja.org/2014/04/05/fedora-encrypting-your-home-directory/ (following "easy way" instructions). This didn't do anything AFAICT, the test user's files still appear to be unencrypted, and I don't see any ecryptfs mount. Any suggestions? Is ecryptfs the way to go here or something else? Thanks, Neal
