Zinc: An Ubuntu remix that dares to be different

LXer Linux News - Sun, 10/16/2022 - 11:28
Impressive distro is somewhere between a tech demo and a power user's tool. While many Ubuntu remixes just switch the desktop or replace a few default apps, Zinc changes some of the fundamentals. The result is impressive.…

Support for Ubuntu applications in Elementary

Linux Questions - Sun, 10/16/2022 - 11:20
I am confused about support for applications packaged for Ubuntu, whether distributed directly by Ununtu or in third-party repositories, in Elementary OS.

I have searched for LibreOffice and Firefox (though the latter is available in Ubuntu only as a snap, unless a further repository is added) in the AppCenter and found neither.

These applications being quite common and popular, it seems surprising that there is no direct path to installing them in Elementary. All around, it seems the offerings from the AppCenter, though they may be carefully curated, are rather limited.

What is the current attitude for Ubuntu packages being installed in a deployment of Elementary OS, and is any path available for installing them outside of the command line?

No longer have two monitors working

Linux Questions - Sun, 10/16/2022 - 11:20
After the last update, I noticed that my second monitor no longer worked. I updated to the latest nvidia driver and still had no joy. I notice now that when I startx, two monitors show in KDE for a bit, and then the second monitor quits.

Any ideas what to look for?

is there a package or substitute for helvetica-bold-r-normal font?

Linux Questions - Sun, 10/16/2022 - 10:57
I compiled xboard, but it will not run without the font helvetica-bold-r-normal.A helvetica font was placed in /usr/share/fonts/myfonts/ and fc-cache -f -v was run to update the font cache, but was not recognized by xboard. xboard wants the exact file.

how to parse values ical file

Linux Questions - Sun, 10/16/2022 - 10:00
The below is an example of a google calendar ical export. There are 3 events in this calendar.
There's a few things I need to find from this ical.

1. what are the events happening in the next hour. For example if it's 07:00, I need to pick up the events from 08:00 until 09:00.
To do this I can run this command
Code: cat grep DTSTART:20221016T05 There's a 3 hour timezone difference hence the 05. I don't know why google calendar ical file shows times in UTC+0 but I can handle this in my script.

2. I need to get the SUMMARY field of the events happening in the next hour. But how can I combine the previous grep command to associate the events happening in the next hour with their SUMMARY?

My Slackware Crashes Frequently

Linux Questions - Sun, 10/16/2022 - 09:46
Hello,
I have been using slackware for more than a year.This is the best linux distribution from my experience.But I am having frequent crash-issues.

I have had more than 30 crashes.My slackware just crashes frequently and I have to shut-down the laptop by pressing the power button deliberately.Sometime I even have two or more crashses in a single day.

What could be the problem?
>>>> Is it a kernel issue?
>>>> Is it a hardware problem?

I can share my syslog and dmesg report if you need.(I am unable (or don't know) to upload them here)

Could this be a cause?
---issue 1---
[ 0.000000] x86/split lock detection: #AC: crashing the kernel on kernel split_locks and warning on user-space split_locks

should I consider turning off the split_lock_detection?

---issue 2---
[ 5.480365] ACPI Warning: \_SB.PCI0.GFX0._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20210930/nsarguments-61)

can I configure the acpi?

My laptop is Dell-Inspiron 5593,i7-10th Gen

Bad DIMM on Linus Torvalds' Desktop System Moves Kernel Merges to His Laptop

Slashdot - Sun, 10/16/2022 - 06:34
When a kernel developer asked Linus Torvalds if he'd missed a Git pull, Torvalds "revealed the request was still in his queue as 'I'm doing merges (very slowly) on my laptop, while waiting for new ECC memory DIMMs to arrive,'" reports The Register: Torvalds needs the DIMMs because over the last few days he experienced what he described as "some instability on my main desktop... with random memory corruption in user space resulting in my allmodconfig builds randomly failing with internal compiler errors etc." The Linux boss's first thought was that a new kernel bug had caused the problem — which isn't good but sometimes happens. His instinct was wrong. "It was literally a DIMM going bad in my machine randomly after 2.5 years of it being perfectly stable," he wrote. "Go figure. Verified first by booting an old kernel, and then with memtest86+ overnight." Torvalds appears to have been tracking delivery of the new DIMMs as he reported replacement memory was "out for delivery" and predicted it should arrive later on Sunday evening.... His post also mentions that his main PC was set up for error correction code memory (ECC memory), but "during the early days of COVID when there wasn't any ECC memory available at any sane prices. And then I never got around to fixing it, until I had to detect errors the hard way." "I absolutely *detest* the crazy industry politics and bad vendors that have made ECC memory so 'special'," he added.

Slackware ARM 15.0 32-bit qt package bug

Linux Questions - Sun, 10/16/2022 - 03:58
Hi!

I've just noticed qt5 is missing from my $PATH

Code: # echo $PATH
/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/usr/games:/usr/lib/libexec/kf5 This seems to be caused by the following files not being executable:
Code: /etc/profile.d/qt5.sh
/etc/profile.d/qt5.csh The problem is the up-to-date qt5 package from patches directory.
The files are executable as they should in slackware/lib directory on the slackwarearm mirror as well as in slackwarearm-current.
I wanted to check what the problem is looking at the SlackBuild, but qt5 source is missing from the patches/source directory for some reason...

For the time being the solution is to make /etc/profile.d/qt5.sh
/etc/profile.d/qt5.csh executable manually
Code: # chmod +x /etc/profile.d/qt5.*sh Regards,
Alex
