On Topic / About CPU over heating

« on: November 13, 2018, 09:58:04 PM »

Sometimes, especially in older machines, the CPU temperature may rise above it's normal threshold.
This is usually not an issue with new CPUs, since they don't consume power so much.

But since we are talking about older computers, over heating may become an issue and I write this topic
about how to deal with it.

First of all, old CPU units tend to consume much power, which leads to heating. there is no way out of the fact.
This is the reason why desktop computers usually have huge cooling units - of various kinds, which themselves
produce again more heat - there is no way out of this thermodynamic fact. The extra heat must go somewhere.
Desktops just "blow away" the heat into room air, which is usually always much cooler.

But how about older laptops. They don't have efficient cooling systems and sometimes the CPU temperature
just hits it's maxium. There are many ways to deal with this situation though. I try to explain some of them here.
The first one is kernel-dependent, meaning that you cannot use it if the running kernel does not support it.
To find out, open the console and command:

Code: [Select]

sudo grep MCE /boot/config-$(uname -r)
If the output has a line like: "CONFIG_X86_MCE=y", then you can use the CPU Machine Exception Banks for
this purpose. Just make sure the service has been enabled by commanding:

Code: [Select]

systemctl status mcelogIf it does not run or has not been installed, then install mcelog, enable and start it:

Code: [Select]

systemctl enable mcelog; sleep 5; systemctl start mcelog
That should do it. Now the kernel is able to communicate with the mce-process, and warn if the temperature
is too high. How to configure the mcelog daemon? Ask! MCElog does much more than just reports about
temperatures, so this may not be the best possible solution to this particular problem.

There are many other ways to deal with this issue, for example using the desktop XFCE sensors plugin, which
brings the CPU core temperatures to the XFCE desktop.

And you may always just read the temperature from /sys: (and maybe use it in cron or by other means)

Code: [Select]

cat /sys/class/thermal/thermal_zone0/temp
Divide that by 1000 and you have approximately the core0 temperature in Celsius, metric units (The Correct ones

Well, I thought I would write more about this topic, but I'll write about "thermald", "lm_sensors" and "SMART" in
other topics if you guys think it might be interesting

Cheers!

Release Announcements / Re: Linux Lite 4.2 Final Released

Just done my first clean install of 4.2.

A very smooth install.....Nice.

Gz bro! Same here, just finished installation and made the updates. No problems at all, as usual with LL.

I have one issue though, which is not related to Linux Lite but the Linux wireless subsystem.
If you are not from the United States of America, please check what the command "iw reg get" says.
For me it always says either:

Code: [Select]

country 00 or

Code: [Select]

country US which are wrong, since I'm in Europe and
some of you are from other regions. Country 00 is always wrong.

One might think this is not an issue since the wireless network works fine. However, if we are accurate, it is a
legal issue, since every country has it's own legal radio frequencies which are available for civilians.
As I said, this is not an issue with Linux Lite, it is an issue with the Linux kernel, or better yet - the lack of it at
the moment.

I am not going into the details of this thing, since it is very simple to fix. You only need to know the abbreviation
of your country: For example, if you live in France, the abbreviation is 'FR'. It is usually just two letters.
So, assuming that you live in France, you would do the following to fix the regulatory domain:

Code: [Select]

sudo iw reg set FR
And you may then verify that the radio frequencies are correct for domain 'France' by commanding:

Code: [Select]

iw reg get
which should now begin with FR instead of '00' or 'US'


If I may help, please ask in this topic since I seem to be blocked in other areas here

Cheers!

Just when I thought Linux could not get much better, the Linux Lite team pulls out 4.2.
Thank you for all the people who work hard with Linux Lite. You make a difference!

@Jerry, I have 21 partitions and 2 RAID1 volumes. My /etc is highly customized,
my /lib/systemd/system is very customized. This box runs kernel 4.19 with
Linux Lite 4.0

Is it safe to upgrade to LL 4.2 with this kind of configuration?

Sorry, I think the answer is that people who mess up their own LL systems like me, have to live with the results

Installing Linux Lite / Re: re-use old live USB for new LL iso?

« on: October 23, 2018, 06:15:39 PM »

I have used USBs for a few linux installs - I failed previously to re-format these, ie to empty them and revert to FAT format. Re-formats usually "succeeded" but only showed a tiny free space, ie didn't effect the live ISO. It's a while ago but I think I tried the formatting on both LL and Win7.

I want to try the 4.0 upgrade, I'm reluctant to use my last clean (32GB!! ) usb. Any suggestions please?

Hi,

You don't need to be worried about formatting the USB, since you can always reformat it after using it
for Linux installation. And, the USB does not need to be formatted at all when you write the LL iso image into it.

I assume you are using Windows. If so, just "burn" the LL iso image to the USB and that's it.
(If you use Linux, and let's say your USB drive seems to be /dev/sdc, then just 'sudo cat imagefile > /dev/sdc' )

Video Cards / Re: No display on HDMI out

« on: October 23, 2018, 05:29:44 PM »

So not sure if this is the right category, but I have HP laptop, AMD GPU, AMD CPU, HP 17-ak001ds . I've connected my TV to the HDMI out on the laptop, but can't get LL to recognize it.
Linux Lite 4.0 (GNU/Linux 4.15.0-36-generic x86_64)

Any suggestions on what to try?

Thanks

What is the output of the command? :

Code: [Select]

sudo grep HDMI /boot/config-$(uname -r)

Start up and Shutdown / Re: Error loop on reboot

« on: October 23, 2018, 04:57:31 PM »

Actually bug in the order, in which system tries to close processes and unmount directories.
When done in inconsistent order, the system shutdown process may hung up, waiting for
another process to free the resource it is trying to access

Start up and Shutdown / Re: Error loop on reboot

« on: October 23, 2018, 04:48:31 PM »

Oftentimes when issued manually to reboot, the system would close up all the processes but somehow fail to proceed. When given input, the terminal would show up, with the last line telling the system is initiating reboot, but further input returns the original black screen, which we had escaped. Further input rolls back to the same terminal sequence, appearing to load again each time anew.

If you are trying to shutdown, reboot or startup and
still find out just a black screen, try this:

Press CTRL+ALT+F2
You should get a login prompt. Login and type 'sudo su'
Then command:

Code: [Select]

mount | grep /dev/sd
If it gives some drives still mounted, then
try to unmount them and if it fails, remount them read-only
by commanding something like: 'sync; mount -o remount,ro /dev/sdX'
where X is the partition you are trying to unmount.

So, first try to unmount the unmounted partitions, if some or all
of them fail, then try to remount them read-only, like said above.
Let's say it succeeded, then just command:

Code: [Select]

sync; init 0and reboot...

But, if it did not succeed, then try:

Code: [Select]

sync; mount -o remount,rw / ;
There are certain race-type bugs in Ubuntu systemd services which cause
these kinds of problems. But, let's fix them, right?

On Topic / Re: Upgrade across releases

« on: October 23, 2018, 02:47:04 PM »

Quite simply put for Ubuntu based distros, sudo do-release-upgrade has a high failure rate and is an extremely complex process that requires specific intervention for each pc. I doubt there's a dev in existence who would dare take on the task of writing GUI software for this process. You could pay me $10k and I still wouldn't do it.

Just installed kernel 4.19 and cannot wait for LL 4.2 - it comes out before Xmas fortunately
It is up to you guys if you can / can afford / cannot support Linux Lite project, and we all have
our special situations. If you have a few dollars /euros etc. extra, just help the team, you help
yourself by doing so.

@Jerry , the LL team and all the LL users: I am sorry if have made some inappropriate comments
here. I am an old guy and I have a business-oriented background, where people usually say
(out of their mouths) what they think at that moment. I understand that these forums have
different rules and I apologize if I have been rude.
Also, what comes to my post about youtube, I didn't realize at that moment that we have different
laws about downloading content there, depending on in which country we live in.
With that said, I hope I've learned my lesson

« on: September 21, 2018, 12:13:16 AM »

Yes, some people need to learn it the hard way.
Do NOT install proprietary sh*t to your Linux.

Ps. @EB , was it really a 'HELPFUL TIP' ?

People are entitled to download proprietary software to their pc. Please don't be preachy in this regard. And yes, his post is useful. Some of you posts lately have been rather aggressive. May I suggest you revisit our Forum Rules. These are not the tones on which our Forum runs. Cheers.

@Jerry ,

To be honest and truthful, you must sometimes be straight. It may not always be so polite but I rather risk being polite
than give false / wrong / crazy / dangerous information to you guys.
And you are right, people are free to mess up their Linuxes as they wish

Ps. @EB , was it really a 'HELPFUL TIP' ?
You can't fine-tune sh*t after a couple of major kernel updates.
Instead, you caused many crashes already, some people are just
not able to report them, because their screens are screwed up

Now I agree with Moltke.
I hate to cause any kind of polemic but at the same time I want to share

@Moltke ,

Did I ever say I want to change my login shell?
If so, would you point the place I did so, please?

And for your information, I don't take instructions from noobs,
I was in this business when you were ~5 years old

Why don't you go and post your chsh-idea to the 'HELPFUL TIP' area?
I answer for you: because it is not a helpful idea!

Do you get it?
