Lenovo-Laptop "Ideapad 120 S - 11IAP" with Intel HD-Grafik 500; insufficient screen brightness

Lenovo-Laptop "Ideapad 120 S - 11IAP" with Intel HD-Grafik 500
insufficient screen brightness

Screen brightness under Linux Fedora (as well as under Linux Lubuntu,
but not under Windows-10!) is completely insufficient, probably due to a
lack of driver. Does anyone know if there is a (simple) way out?

Thank you, greetings

I am running Fedora28LXDE on a Lenovo Ideapad 120S-11IAP with its Intel

like that)?

Change language operating system

Under Fedora 27 Mate I try to change the language of the operating
system, e.g. from German to French.

Thunderbird, opening by double-click mails which are saved outside
Thunderbird-GUI (Fedora-LXDE)

Preliminary note:

Since a couple of years I am running Fedora-LXDE with Thunderbird as my
only mail-client. Each time I receive mails, I save all important mails
outside the Thunderbird-GUI, in the folders they factually belong to
(tax, banking etc.), and then delete them in the Thunderbird-GUI.

Setup Fedora on UEFI-Laptop

On a new Laptop (UEFI / Secure Boot / GPT-specific partitions
"EFI_System_Partition" and "Microsoft_Reserved_Partition") I intend to
replace the pre-installed Windows-10 with Fedora-LXDE which will then be
the only system on the hard disk .

When installing Fedora, have I to preserve both of the two partitions
"EFI_System_Partition" and "Microsoft_Reserved_Partition", or can I wipe
both of them or one of them?

Thanks in advance.

Opening email messages in Thunderbird under Fedora 25 (and older versions)

older versions)

Case 1:

I receive an email message in Thunderbird, this message remains INSIDE
the Thunderbird-GUI and I do NOT delete it there:

In this case I can open the email message without any problem, as often
as I want to do it.

Case 2:

I receive an email message in Thunderbird and open it inside the
Thunderbird-GUI. But as I see the message is important, I decide to
- save it OUTSIDE the Thunderbird-GUI for further use, e.g.

Fedora 25 LXDE, Start Menu, Developer > Elementary Tests

After upgrading to Fedora 25 (LXDE) I found a new line

in the start menu. Does anyone know the name of the package which
corresponds to this application? Thanks.



Fedora 24 LXDE; how to remove duplicates

In my Fedora 24 there are a lot of duplicates, i.e. multiple versions of
the same file (one or even two old versions and one new version). Which
made correct upgrading to Fedora 25 impossible.

Does there exist an easy and simple way (e.g. in DNF) to remove ALL old
versions in ONE step? Or have I to remove them all one by one?

Thank your for your help


FedoraLiveWorkstation on external hard disk

FedoraLiveWorkstation on external hard disk

Additionally to my laptop (Win7 and Win10 in dual boot mode; UEFI and
GPT-partitions) I should like to setup Fedora on an external hard disk.

But whatever I try, the setup routine always recognizes only the
internal hard disk with Windows 7/10 and it never recognizes the
external hard disk.

What am I doing wrong?

Thank you for your help

Opening Mails in Thunderbird (under Fedora 23)

Opening Mails in Thunderbird (under Fedora 23 and older versions)

Each time I receive mails in Thunderbird, I can open them without any
problem, but ONLY as long as these mails remain INSIDE the Thunderbird-GUI.

But as soon as I store a mail OUTSIDE that graphical user interface,
e.g. on a usb-stick or elsewhere on a hard disk, it is impossible to
open again that same mail with Thunderbird.

Fax-Client for Fedora LXDE 32 bit

Fax-Client efax-gtk in Linux Fedora LXDE 32 bit


I installed efax-gtk in Fedora 22 LXDE on my laptop, in order to send a
fax from time to time; when I open efax-gtk in Terminal as a root, I
receive this error-message:


[root@localhost andreas.assmann]# efax-gtk

efax-gtk in Fedora 22


I installed efax-gtk in Fedora 22 LXDE on my laptop, in order to send a
fax from time to time; but I always receive this error-message:


efax-0.9a: 17:12:45 Error: can't open pre-lock file
/var/lock/TMP..02390: Permission denied
efax-0.9a: 17:12:45 failed page /home/username/example.pdf.001
efax-0.9a: 17:12:45 finished - unrecoverable error


I don't understand this, because there is absolutely no tmp-file in
/var/lock/, only five folders (iscsi, lockdev, lvm, ppp, subsys) and a
file "asound.state.lock".

Has anyone an idea of what is going wrong?

Fax-Client for Fedora LXDE 32 bit

Fax-Client for Fedora LXDE 32 bit


I set up Fedora LXDE on a 32 bit machine and I am now looking for a
simple fax-client, if possible with a graphic user interface. I am still
a beginner.

I found "efax" in the repository, but there is unfortunately no graphic
user interface, and I was unable to handle and configure efax in the
Terminal. On the other hand there exists a gui "efax-gtk", but not in
the Fedora-repository.

Mobile Broadband device (USB-modem) on Fedora 22

Mobile Broadband device (USB-Stick) on Fedora 22

Hallo everybody,

I installed a new Fedora 22 LXDE (32 bit) on a laptop; unfortunately
Fedora 22 doesn't recognize the USB-Stick.

When I do "dmesg" as superuser, I get the result copied below. The
device is "detected", but it doen't appear on the desktop nor is it
possible to get it work.

Has anyone an idea about what I got to do in order to get it work?

Thanks, best regardsin

Multi-Boot-Laptop (Windows7 / Linux Fedora 20 LXDE); Error message "Could not configure common clock"

I have been running Windows7 and Fedora20LXDE on the same laptop for
more than one year, but the other day, for the first time, there was an
error message "Could not configure common clock" and a complete boot
hang. By no means I could restart the computer, neither in Windows nor
in Linux.

Does anyone know,
- why this occurs and
- how I can prevent it?

Thanks. Best regards

KeePass in Fedora; Change Language


I use password-manager "KeePass2" in Linux Fedora.

Does anyone know how I can change language from "English" into "German"?
I found the downloads under <a href="" title=""></a> , but:
- do these files fit in Linux and, if yes,
- where do I have to install or paste them?

Thanks for your help.

Password-Manageer KeePass2 (Windows) / KeePassX (Linux)


I use the password-manager "KeePass2" in Windows since a couple of
years, and should also like to use "KeePassX" in Fedora. But up to now I
could not transfer my passwords from "KeePass2" to "KeePassX".

Does anyone know a simple way to do that?

Thanks for your help.

BroadbandModem (USB-Stick)

I tried to connect with Internet by means of a broadband modem (USB-Stick).

It works fine on my laptop with Fedora 19 (LXDE).

But it does NOT work on my laptop with Fedora 20 (LXDE).

Has anyone an idea, where the reason might be? Thanks for you help


Package manager "synaptic", two kernel-versions

After upgrading from Fedora_19 to Fedora_20, the package-manager
"synaptic" informs me that I have now not only

kernel#3.14.2-100.fc20 and

but also the old versions

kernel#3.13.11-100.fc19 and

I tried to delete the old versions by using the package-manager
"synaptic" but it simply doesn't work, "synaptic" cannot delete
"kernel#3.13.11-100.fc19" and "kernel-modules-extra#3.13.11-100.fc19".

Does anyone know another solution?

Fax in Fedora


in order to send a fax, I installed hylafax+, hylafax+client and uucp.

Can anybody tell me what there is wrong and how I can get it work?


Connecting to Internet in a Hotspot

Can anybody tell me if connecting to internet in a public hotspot is
safer with Linux (Fedora) than with Windows? Or is it all the same?

Opening E-Mails

Opening E-Mails

On my 64bit-laptop I have two operating systems in dual-boot-mode
(Windows7 and Fedora19LXDE), and a separate partition („Own Files“)
where I store my private files, e.g. important e-mails (*.eml). My
e-mail-client in both operating systems is Thunderbird.

When starting my laptop from out Windows7, I can open and read without
any problem all e-mails stored in the partition “Own Files”.

Fedora 19, Music in Youtube

I installed Fedora 19 on two laptops (one 32 bit and the other 64 bit).
In the beginning, after the initial installation of Fedora 19, I could
listen to music videos on Youtube on both of the two laptops without any
problem. But at a certain moment, I could not hear anything any more (in
the video, there is now a little "Andrew cross" on the right side of the
loudspeaker symbol).

Does anyone of you have an explanation or even a solution for this
problem? Is there an incompatibility with updates installed AFTER the
initial installation?

Thanks so lot. Greetings


Fedora19 LXDE; system-config-keyboard

In a new Fedora19 LXDE I installed "system-config-keyboard" inorder to
change keyboard from English to aGerman. But when I click on the newly
appeared line "Keyboard" in the menu, there is no reaction at all and
the keyboard remains English. Is there a bug?

Upgrade Fedora17 > Fedora18 with fedup


I upgraded my Fedora17 with fedup, today, and everything went well with
one exception: Eachtime when my new Fedora18 boots and each time when it
shuts down, it shows to bug-lines:

dracut-cmdline[45]: Warning: Kernel command line option 'KEYTABLE' ist
dracut-cmdline[45]: Warning: Kernel command line option 'SYSFONT' ist

What can I do to repair this? I am a Linux-beginner.

Thanks, best regards
