The same laptop has been tested on Windows and Ubuntu. The heating issue
was present on those operating systems.
It seems to be a Fedora specific issue. How do I go about fixing it?
My problem is exasperating... I have a canon mf624cw on my
network. It has been there for a couple of years and worked well. when I started to work on my tax stuff, downloads etc. it refused to print. I powered down the router and repowered it. This usually worked because I have MANY systems on my home router wirelessly (about 15 at any one time), so occasionally it loses its little bitty mind. Not ofter, maybe once every 4 or 5 months.
Now given that this didn't bring the printer up, I then did a
ping and the printer responded. Lpq shows the printer not accepting
jobs. Brought up settings, and attempted to delete the printer. NO
JOY. I would unlock, authorize, delete the printer, close the
notification window, close the printer window and settings, reboot just
to make sure the settings took, and bring the system back up.
The printer was still there. Answered pings etc. OK, maybe
the printer has an issue. Powered down the printer, left it over
night, reset it and got the network up on it, confirmed I could ping
it, but still no printing.
OK, maybe the driver or the que is messed up. Again tried to
delte the printer while it was off. No joy. Went to Google, but it
was not my friend in this case.
So after three days of this, I am surrendering to the greaterwisdom.
System is AMD FX 8300 at 2.8Ghz, 15.6GiB memory, AMD Oland,
Gnome 3.28.2 64bit, lots of disk space. Just updated by dnf.
dmesg doesen't show any problems
journalctl doesn't show my any printer stuff.
Printer shows no errors.
printer shows network and can be pinged.
What I think I need is to remove all system references to the
printer. I have tried grep on the /etc directory and sub directories,
but no joy on locating the entries for the printer.
If anyone can tell me all the locations where the printer is referenced
and how to remove the references, I will probably be able to bumble my
way out of this. Or any other suggestions that might work.
Remember I have tried the gui from settings, and the cups 631
network page but with no joy on either. If you think I need to try any
of those again, please post step by step so I can be sure I do what you
In order to install the KDE Desktop I used DNF to install the
KDE-desktop-environment group, which place a plasma entry in the desktop
manager desktop list, but selecting this entry did not boot into KDE, it
just continued to display the Desktop Manager. It wasn't until I
manually installed, I think, the plasma-workspace-wayland that 'plasma
for wayland' was added to the desktop list in the display that did
enable KDE to be started. Given that it seems that F29 is standardizing
on Wayland instead of Xorg, why doesn't the KDE-desktop-environment
group also install this package to provide the needed Wayland support so
KDE can be started under Wayland, rather than require the user to
install it manually?
I'm trying to enter Chinese characters using ibus (Intelligent Pinyin).
As I enter the pinyin spelling, the Chinese characters show up in small
menu. The characters are displayed in a small font that my old eyes
have trouble reading. I want them to display in a size 16 kai font (AR
PL Ukai CN). I ran ibus-setup, and it is set correctly. I also have
the file ~/.i18n which has this line:
What else do I need to do?
I have burnt a Fedora 29 workstation live install to DVD and tried
to boot it with the bios set to UEFI mode, but it halted with a boot
error. Thinking there might be an error with the DVD I downloaded a tool
for windows that allowed me to download and burn the F29 installer to
usb, but this failed to boot with the same issue as the DVD. If I
switched the bios into legacy mode both the DVD and USB successfully
booted to the Fedora desktop. From what I have read on the net the live
installer is dual setup, in terms of the documentation said that if the
installer was booted in UEFI mode it would perform a UEFI install and if
it was booted in legacy mode it would do a bios install, so given this
have I done something incorrectly to cause the installer to not boot in
Having set my hard disks up in Raid 10 mode I booted the F29
installer in bios mode which successfully booted to the desktop, where I
selected the install to hard disk option which worked fine up to the
point of setting up the disks, where the disk setup could not see any
disks at all to configure for installation. From what I've read on the
internet the workstation installers for F22 through F24 did not support
raid but the equivalent server installers did. Has this still not been
rectified up to the F29 workstation installer?
I have two email accounts, one at my local access
provider, and one on my own domain, hosted remotely. I'm running Fedora
29. Last time I looked, my host was running Centos. Now I see this:
$ uname -a
Linux <x.y.z> 2.6.32-042stab134.3 #1 SMP Sun Oct 14 12:26:01 MSK 2018
x86_64 x86_64 x86_64 GNU/Linux
Is something there the name of a distro?? (I've forgotten the
proper command, with 'release' in it,for asking a remote machine what
it's currently running.)
It's past time I ought to've downloaded a mass of cruft (old
emails) from my host's machine, stored them on some medium here (Maybe a
nice external solid state 2 Tb drive?), and gotten them out of the way.
They're slowing me way down.
I've never gotten around to learning rsync, nor even trying
Grsync. Last time, istr, I made do with cpanel at the host. Now the host
has something new to me, WHM, in front of cpanel, and I haven't the
faintest inkling what all it can do. Is there now good strong new EASY
magic for a subtechnoid like me to do the old chore, or should I just try
to recall how I slogged through before? I feel like a sorcerer's
apprentice, and don't want to drown in cyberspace.

Remember I know little (precious little!) of where up is.
Could you recommend affordable and reliable cloud storage for 50 TB of data?
Here are some important factors to consider:
1. Personal/non-commercial use.
2. Must be affordable, since I am unemployed most of the time and have
super low levels of income for the past 12 years since I graduated
from the National University of Singapore in 2007.
3. Cloud storage provider must not be a fly-by-night company, that is,
it will not suddenly close down the next day.
