Re: computer screen blink

[lina]

Thanks all, I have changed the source.list

I need to reboot the computer but I'm still waiting for some jobs to finish
before I can reboot.

Thanks all, lina

I'm not sure what this is meant to show. Looking at the timestamps,
this machine was booted at about tea-time yesterday, but some of
the software that might be required was only downloaded and installed
this morning. I think it needs rebooting.

Cheers,
David.

If she's running bullseye (or trying to do so), she'll need to change
the security line as well.  It's still in the old "buster/updates" format.

You should never use the word "stable" in your sources.list.  This
is going to cause you immense problems when a new version of Debian
is released.  (This may already have happened to you.)

If you're running a stable (or older) version of Debian, you should
use its release codename in the sources.list file instead.  E.g.
"buster" or "bullseye", where you have "stable".

This looks like it's the sources.list from a buster (Debian 10) system.
I can tell, not only because you have buster-backports listed, but
also because of the format of the debian-security line.  This file is
still using the older "releasename/updates" field, rather than the
newer "releasename-security" field which began with bullseye (Debian 11).

If this is the case, I would urge you to change all instance of "stable"
to "buster" immediately.  Before you break anything (more?) by accident.

This cpu does not have a built-in GPU, so this is not a problem.

Ok, did you install the nvidia-packages for your graphics card? 
If yes, please make sure, you blacklist the nouveau kernel module.

If not, you may try these.

If you do not want to use the nvidia-drivers, then make sure, the driver 
correct GPU is adressed. There are sometimes notebooks with 2 graphics cards: 
one is built within the cpu (especially intel and amd), and the other one is 
external. Make sure, that only one graphics card is accessable (I would choose 
the better one withg 3d acceleration). To do so, you might either deactivate 
it in BIOS (but that may not work!) or use some software solutiuon like 
bb-switch or similar (it is in the repo).

Also check, if you set the correct solution. This can be forded by using 
xorg.conf (today xorg.conf is generally no more needed), but with an existing 
xorg.conf you are able to force things.

When you have got a blank screen only at boot time but then it is ok when 
starting X, then two reasons might be reponsible: 1. Your graphics card or 
mnonitor can not switch to vesa-mode (this problem appeared at my system), or 
your monitor can not work the choosen resolution.

If your monitor is blank at all, then it looks like a wrong set resolution. 
Play with xorg.conf.

If your internal monitor is blank, and the external is working fine, it is 
either a bios setting problem or a setting in your window manager.

If the internal is fine and the external is blank, check the settings in your 
window manager.

On my own system I can not show both screens at boot, only the external is 
shown. This is a bios problem by the manufacturer (Siemens Amilo Notebook) and 
can not be fixed.

Hope this helps a little bit.

Best regards and good luck!

My mistake, you are using the stable Debian:
you may replace the buster-backports by  bullseye-backports

Hi Lina,

This is a relatively new computer. Do you have the non-free AMD firmware
isntalled?

The packages you probably want are firmware-misc-nonfree and
firmware-linux-nonfree

Does the /etc/apt/sources.list file include entries for contrib and 
non-free?

What is the model of your video adapter: if I remember, you have an NVidia
card in there? [Nvidia GT730]. Optionally, you can install proprietary
Nvidia drivers -
https://wiki.debian.org/NvidiaGraphicsDrivers#Version_460.91.03 


Hope this helps narrow down the problem.

All the very best, as ever,

Hi Lina, so you are mainly playing with a server and you are certnaily used an 
external monitor.
Have you tried with a totally different monitor ?
Are using a VGA terminal or Xorg windows ?
What does dmesg gives against nouveau ?
As root:
# dmesg | grep -i nouveau
What is you actual kernel:
# uname -a

Re: computer screen blink

[Andrew M.A. Cater]

Hi Lina,

This is a relatively new computer. Do you have the non-free AMD firmware
isntalled?

The packages you probably want are firmware-misc-nonfree and 
firmware-linux-nonfree

Does the /etc/apt/sources.list file include entries for contrib and non-free?

What is the model of your video adapter: if I remember, you have an NVidia
card in there? [Nvidia GT730]. Optionally, you can install proprietary
Nvidia drivers - 
https://wiki.debian.org/NvidiaGraphicsDrivers#Version_460.91.03

Hope this helps narrow down the problem.

All the very best, as ever,

Andy Cater

Hi Jerome,

It is not a Mac computer.

It has only one System, Linux.

The hardware should be fine as it happens after A BIG UPdating of the

Re: computer screen blink

Hi Andrew,

I have fixed the updating system. Now it looks like this:

# aptitude full-upgrade
No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B of archives. After unpacking 0 B will be used.



It is just blinking, nothing warning signs shows up.

It happened after my last update.

Re: computer screen blink

[Jerome BENOIT]

Hi,
you may fist determine if it is a hardware issue or a software issue.
Some Mac screens are known to flicker after a while.
What is your computer ? Can you boot on Windows/MacOS to see if the same thing 
happens ?
Knowing your hardware may help a lot.
hth,
Jerome

First things first: update your computer. Security fixes and fixes for
other problems come out all the time.

What Debian version are you running?

On what sort of computer?

Do you have screensavers or similar kicking in?

is there a temperature issue?

Are there logs?

A little more information would be helpful.

All the very best, as ever,

Hi Lina

Try running aptitude update - to pull the updated list of packages - then
aptitude full-upgrade - you shouldn't see those sorts of inconsistencies.

Bullseye - Debian 11 - OK.

Temperature issue - only thinking that if it was something that only
happens after a long time, it might be because a componetn inside your
screen warms up / misbehaves.

Does anything else happen just before it all locks up?

First things first: update your computer. Security fixes and fixes for
other problems come out all the time.

What Debian version are you running?

On what sort of computer?

Do you have screensavers or similar kicking in?

is there a temperature issue?

Are there logs?

A little more information would be helpful.

computer screen blink

[lina]

Hi all,

After using the computer for a long while, my screen will blink.

It has been months since the last time I upgraded the system.

I don't know how to start checking, every time I have to reboot the
computer,

would be great to get your advice,

thanks,
