may I contextually remove, always via terminal, the old kernel before  
rebooting


That would be a bad idea: if, for some reason, the newer kernel does not  
boot, you could not boot the older one.


will I encounter other problems?

The problem should not have happened in the first place.  It apparently deals  
with the generation of GRUB's configuration file.  Maybe the disk is failing.  
 Have you checked its SMART data, for instance using GNOME Disks  
("gnome-disk-utility" in Trisquel's repository)?


[Trisquel-users] Re : kernel panic after upgrade

2020-02-09 Thread lcerf

I have a kernel panic situation after doing apt upgrade.
I forgot to do autoremove and autoclean. My fault.

apt's autoremove and (auto)clean command only free disk space: not using them  
is not the cause of your problem.


I dont´t see the option to use another kernel.

Do you see GRUB's menu before the kernel boots?  If so, select the "Advanced  
options for Trisquel" (or something like that) and then another kernel (not  
the first one that is listed).


I connect the USB, try to install and it says cannot do because kernel is not  
started.


You chose to directly install from the initial menu, right?

I think the problem is no space in boot partition.
How can I get terminal to do just that?

Boot into the live system, mount the filesystem on your internal disk (the  
one attached at /boot) and execute 'df ' in a terminal.


I would bet on another problem though: your ext4 filesystem on sda2 looks  
corrupted ("unable to read superblock").  'fsck -y /dev/sda2' may be all you  
need to fix the corruption.


[Trisquel-users] Re : Kernel 4.4.0-143 in 2019?

2019-06-26 Thread lcerf
Version 4.4.0-143 was indeed released this year.  According to APT's logs on  
my system, I had it installed on March 20th.  As chaosmonk explained, it is  
the 143th security update of the 4.4.0 version, which was released in 2016,  
and there will be such updates until the end of the support of Trisquel 8.

https://www.fsfla.org/ikiwiki/selibre/linux-libre/ is the homepage of the  
Linux-libre project.  The resulting source code is then compiled and packaged  
to be easily installed (by package managers).  Jxself not only works for that  
project but also packages the kernels for distributions that use APT,

Are you referring to Meltdown and Spectre?  Those attacks have absolutely  
nothing to do with the Management Engine.


Having up-to-date is important to be protected against known attacks such as  
Meltdown and Spectre.  Newer kernel may better support your hardware too,  
especially if it is recent.  And, well, there are other features and  
improvements that are added to newer versions of the kernel.


[Trisquel-users] Re : Kernel problem?

2017-08-20 Thread lcerf
I assume you still have the desired kernel installed.  Otherwise, install it  
again.  You must then boot that kernel: choose it in the "Advanced options"  
of the GRUB menu... but a user and a password will be asked: the user is  
"grub" and the password is at the very end of the output of 'sudo cat  
/etc/grub.d/01_PASSWORD', to be executed in a terminal.  But you had better  
get rid of that useless password (GRUB's developers say so!):

Then, remove the packages coming from jxself's repository.  It is easy to do  
so from the "Synaptic Package Manager" in the "System Settings": click on the  
"Origin" button (bottom-left part of the window), select the repository  
"stable/main (linux-libre.fsfla.org)" (above), click on the "S" header to  
list the installed packages first, select them (left click on the first,  
Shit+left click on the last installed package), right click on the selection  
and "Mark for Complete Removal".  You must then "Apply" the desired changes  
by clicking on the eponymous button and confirming.


If you want to, you can then disable or even remove jxself's repository.   
Still using the "Synaptic Package Manager": "Other Software" tab in  
"Settings/Repositories"; or launching that same utility, "Software &  
Updates", directly from the "System Settings"; or editing  
/etc/apt/sources.list; ...


[Trisquel-users] Re : Kernel panic, what happened?

That is probably caused by a bug in the kernel. But if you cannot reproduce  
the panic, it is pretty hard to guess where the bug can be.

Compiling is (quite) easy:

Configuring the kernel is the hard part. The Gentoo Handbook used to be (and  
probably still is) a good first documentation on the topic:

I doubt you are looking at the proper row of the output table returned by  
'free' (1 GB used after the boot is a lot). You must look at the row -/+  
buffers/cache.


It is very weird that Disks sees a SSD that GParted does not! Are you sure  
it is not the live USB you booted?


[Trisquel-users] Re : Kernel panics

2015-02-21 Thread lcerf
I do not understand much of what you wrote. I was only suggesting you to test  
the disk. The whole disk. If the disk is failing, you need to change it.  
There is no fixing.


The swap is some disk space (a partition in your case but swap files exist  
too) used as (a very slow) main memory when the RAM is full. You can disable  
the use of all the swap with 'sudo swapoff -a' (valid until the next reboot).  
You can also control the relative weight given to swapping out runtime  
memory: https://en.wikipedia.org/wiki/Swappiness


From a Live media (such as Trisquel's ISO, which includes GParted), you can  
create/delete/enlarge/shrink partitions (including a swap partition) but be  
careful: /etc/fstab (that of the installed system, not that of the live  
system) must be changed accordingly.


As far as I understand, the framebuffer is in the RAM (nothing to do with the  
disk, even if the system swaps). When you reduce it from the BIOS, you  
increase in parallel the RAM the system can use and decrease the use of the  
swap. As a consequence, if the disk is the culprit, the IO errors may be  
delayed thanks to that. Anyway, you do not want to use a failing disk!


That said, because the problem occurs as well with a live system, it might  
more probably be a problem with the RAM... although I think GNU/Linux live  
systems can use the swap partition on another disk in the system (I am not  
sure but you could run the live system after disconnecting the internal drive  
just to see if the problem disappears).


Anyway, 1 GB of RAM is too little to run the normal edition of Trisquel (that  
is why it swaps). You want Trisquel Mini.

It looks like you have an hardware issue. I hope you frequently backup your  
data! Have you recently auto-tested your drive? You can do that from the  
Disk utility in System settings (use the menu button in the upper-right  
corner of the windows).


I would try to properly define permanent mount points for your external  
devices ans see if that solves your problem:

[Trisquel-users] Re : Kernel panics

/dev/sdX (where X is a letter) is not a mount point (that must be a  
directory). It is a device. It should contain some partition(s) /dev/sdXY  
(where Y is a number). Such a partition can mounted wherever you want. For  
instance, to mount the partition 1 of the disk b on /mnt:

$ sudo mount /dev/sdb1 /mnt

That said, suspension should not create such problems. Are we talking about  
partitions mounted at init? If so, how are they identified in the first  
column of /etc/fstab (by UUID, by label or the device node)?


Memtest86+ is not on Trisquel ISOs. That means you cannot test your memory  
with the Trisquel live system (well, actually, you can with by install  
memtester that does not require a reboot). You can install the memtest86+  
package on Trisquel though.

[Trisquel-users] Re : Kernel panic after using compat wireless and trying to get wireless card to work

2012-04-09 Thread magicbanana
This compat-wireless stuff is an alternative Linux kernel (probably filled  
up with proprietary code), isn't it? You can probably start a Live system  
(for instance the Trisquel Live system you have used when installing the OS),  
download an image of Brigantia's kernel (here:  
http://packages.trisquel.info/brigantia/linux-image-3.0.0-17-generic ),  
'chroot' to the install system and install the downloaded package with 'dpkg  
-i'... however you need to be motivated to learn the use of a terminal! If  
so, search the web for 'chroot' and list us the exact commands you plan to  
execute.


Otherwise, just reinstall. Anyway it can even be faster (assuming you have  
not had enough time to customize your system with many additional  
applications, etc.). Be careful with your data. If your /home is not on a  
separate partition, you need to backup them (using, again, a Live system).


As for hardware requiring non-free software, the recommendation is to switch  
to freedom-friendly hardware such as everything you can find on
