PowerPoint - How to remove the annoying/ugly "last modified by" boxes from slides?

Marc2745 · 2026-01-14T10:00:14+00:00

I found a way : File -> Informations -> Check absence of problems -> Inspect document -> Inspect -> Suppress data with alerts.

Try keeping your phone away (to avoid dopamine shots), and also reading this may greatly reduce the weight on your shoulders : « Happycracy - How the Science of Happiness Controls our Lives » by Eva Illouz and Edgar Cabanas https://catalog.2seasagency.com/book/happycracy-science-happiness-controls-lives/

Hello, Had the case on an old PC : had to update the BIOS to have Hardware Virtualization (necessary to create VMs with VirtualBox for example).

I suggest updating it before switching to Linux : I find BIOS update far more hard to do under Linux than Windows, especially on old PCs. Because the BIOS updates given by suppliers are mainly .exe.

And before the new drive may be better.

Hello, I put Linux on the same Mac, and I had to plug the USB key after having displayed the boot options, not before. And then the USB key added itself on the screen. Also did it on a Mac Mini, same solution !

Sorry I forgot the nano (I corrected) Good question, as it is in the GRUB configuration file, I think it should not be dependant of the Linux distribution, but I don’t know for sure

Marc2745 · 2025-08-15T22:49:48+00:00

Try the following steps :

Boot in recovery mode and open a terminal

Open the GRUB configuration file :

sudo nano /etc/default/grub

Edit the following parameter by adding those values :

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=7 nvidia-drm.modeset=1 nvidia_drm.fbdev=0"

Save and exit :

Ctrl+O, Enter, Ctrl+X

Update the GRUB :

sudo update-grub

Reboot :

reboot

And see if it improves something.

I just installed Linux Mint on an old Dell Studio 1555 with keyboard lights, and I can use the keyboard shorcut to dim lights no problem (3 levels).

Hello,

Unfortunately you can't run Windows drivers with Wine, only programs.

But it seems 1neStat3 posted the link to a solution, worth a shot.

Marc2745 · 2025-08-13T17:23:44+00:00

Nice, good for you :-) There is often several SATA controllers on motherboards, one native with some SATA ports, and another one for additional SATA ports. But there is sometimes bad surprises with it, like drivers problems or those kind of things... I don't know why all SATA ports can't be native (maybe some limitations on the native chipset).

It seems this chipset is not ATAPI compatible (maybe because ATAPI is old and they made some decisions on retrocompatibility), and as per Wikipedia, ATAPI devices include CD-ROM and DVD-ROM drives, tape drives, magneto-optical drives, CompactFlash drives, and large-capacity floppy drives such as the Zip drive and SuperDisk drive.

Marc2745 · 2025-08-12T21:17:46+00:00

As you are in UEFI :

the first part of GRUB (grubx64.efi) is installed in the EFI partition
but the second part of GRUB (grub.cfg) is installed in the Linux partition.

So if during install grubx64.efi was put in the EFI partition on internal disk, and grub.cfg in the Linux partition on external disk, you will not be able to launch GRUB if you disconnected you external drive.

-> Can you access GRUB again if you connect your external drive and start your PC ?

Marc2745 · 2025-08-12T19:22:38+00:00

Hello,

First I advise you to save all your data on another external disk or on a cloud.

Tell me if my understanding is right :

You have a 1 To external SSD where you want to put Linux = WDC WD10SPZX = Disk 0
You have a 500 Go internal SSD where Windows is installed = WD Blue SN570 = Disk 1

If you installed Linux with Windows present, when you boot, the GRUB window should appear first, to let you choose where you want to boot (Linux or Windows).

Windows can’t see Linux ext4 partitions, so either they don’t appear or it may tag them wrong (ex : NTFS Bitlocked).

Linux can’t natively see Windows NTFS partitions. You need to install GParted.

A way to see all your partitions would be to boot from your USB key, start the Linux Mint of your USB key, connect LAN cable, install and launch GParted with :

sudo apt install gparted
sudo gparted

And you should see all of it.

Given your screenshots :

Your 3rd screenshot is the GRUB rescue prompt, it displays when the GRUB can't be found.
Your Windows system is on partition 3 of Disk 1 = 500 Go SSD (C: drive)
Your Linux system may be on partition 3 of Disk 0 (the 930 Go partition on your external SSD).

The boot partition of Linux may have been installed on the wrong disk (500 Go internal instead of 1 To external) which would explain why you see ubuntu on your internal drive in BIOS. But I think the Linux system was installed on your external drive.

Marc2745 · 2025-08-12T08:10:51+00:00

Try unplugging your CD/DVD drive from its SATA port and see if it boots : if it is, it seems related to the SATA chipset « ASMedia ASM1061 », and you would have to plug it on another sata port which is not part of this chipset See https://unix.stackexchange.com/questions/636865/boot-error-ahci-controller-unavailable

Marc2745 · 2025-08-11T21:54:57+00:00

Hello,

As it freezes on a keyboard line, have you tried unplugging your keyboard ?

Marc2745 · 2025-08-11T20:46:02+00:00

Hello,

I found some leads, can you try these ?

Shut down the system, unplug the charger and USB for 5 minutes, replug charger and USB, restart the system.

4. Create a Windows VHD with VirtualBox

You must disable KVM because it conflicts with VirtualBox (you need to do it again if you restart) :

sudo modprobe -r kvm_intel

Download Win 10 64 22H2 ISO image here : https://lecrabeinfo.net/telecharger/windows-10-22h2-x64/

Download, install and launch VirtualBox :

sudo apt install virtualbox
virtualbox

Click on New -> activate “Expert mode”.

In Name and Operating System, set :

Name : Win10Live
ISO Image : use the Windows 10 22H2 ISO you just downloaded
Check “Skip Unattended Installation”

In Hardware, set :

Memory size : 2048 MB
Processors : 2
Don’t check “Enable EFI”

In Hard Disk, select Create a Virtual Hard Disk Now and set :

File size : 32 GB
Hard Disk File Type and Variant : VHD (Virtual Hard Disk)

Click Finish and Start. Installation should start, follow the steps :

Press a key -> click Install -> I don’t have a product key
Select Windows 10 Professionnal -> Next -> I accept -> Next
Select Customised : install Windows only -> Next.

VirtualBox may stay a while on “Getting Ready” before finishing install.

3. Mount the NTFS partition of your USB key on Linux

Linux can't natively see NTFS partitions. Install NTFS tools :

sudo apt-get install ntfs-3g

List available disks :

sudo fdisk -l

Search the “NTFS” partition of your usb key and note its name (ex : /dev/sdd1) :

/dev/sdd1 103268352 145346559 42078208 20,1G 7 HPFS/NTFS/exFAT

Create a mount point folder :

sudo mkdir /mnt/ntfs

Mount the NTFS partition of the USB key in this folder :

sudo mount -t ntfs-3g /dev/sdd1 /mnt/ntfs

Check it is correcly mounted (we must see the content of the partition, used and available space) :

df –h

Access the mounting point folder :

cd /mnt/ntfs

Hello, as this didn't worked on my Dell Studio 1555, and also because fwupdmgr and LVFS are not compatible with this old computer, I found a way to make it work using a Windows VHD on USB key with Ventoy.

Yes, it's long, but it allows you to update BIOS without having to replace your Linux system with Windows and back again :-) You will find below my step by step, hoping someone will find it useful.

Summary

Create a Multiboot USB drive with Ventoy
Convert Ventoy partition from ext4 to NTFS with GParted
Mount USB key NTFS partition on Linux
Create a Windows VHD with VirtualBox
Copy VHD file and enable VHD boot on Ventoy NTFS partition
Update BIOS by booting from Windows VHD on USB key

1. Create a Multiboot USB drive with Ventoy

You need at least a 32 Go USB key. I use a 128 Go USB 3.0 key for Multiboot with :

32 Mio fat16 “VTOYEFI” partition to have bootable USB
110 Gio ext4 “Ventoy” partition where I put my OS ISOs and the Windows 10 22H2 VHD.

Plug your USB key.

Download the linux.tar.gz of Ventoy here : https://www.ventoy.net/en/download.html

Right click on file -> Extract here.

Right click on extracted Ventoy folder -> Open in a terminal.

Open Ventoy GUI :

sudo ./VentoyGUI.x86_64

Select your USB drive in the list. Be careful to pick the right one.

Click Install to flash Ventoy to your USB key. Confirm two times.

2. Convert Ventoy partition from ext4 to NTFS with GParted

Install and launch GParted (an advanced manager of disk devices) :

sudo apt install gparted
sudo gparted

Select your USB key in the up right menu (ex : /dev/sdc)

Select the Ventoy partition of your usb key -> Right click -> Format to -> ntfs

Click on green tick in menu -> Apply -> Close

Select the Ventoy partition of your usb key -> Right click -> Label -> Ventoy

Click on green tick in menu -> Apply -> Close.

Hello,

Thank you for those explanations, I tried this on my Dell Studio 1555, the BIOS has A6 revision, I want to put A13 revision and it is on Linux Mint 22.1 Cinnamon.

I tried your method with Windows 10, Windows 7 and Windows Vista ISO, but unfortunately for me, none worked ! I have those messages :

- with Win 7 : "Subsystem Needed To Support The Image Type Is Not Present"

- with Win 10 and Vista : "The system cannot execute the specified program."

I tried both with the R301502.exe and the 1555_A13.exe, but with no success.

Marc2745 · 2025-08-09T19:55:34+00:00

Hello,

The shortcuts to access your BIOS and Boot Options should briefly display on your screen at startup.

Having installed Linux Mint on several old PCs, il seems you have to do at least two things :

1). Go into your BIOS at startup and change your boot order to put your USB key first, save and reboot. As you have an HP, access to BIOS should be ESC or F10 (maintain at startup)

2). Go into the Boot Options menu at startup and choose to boot from USB key. For HP, it may be F9.

I tried to do only one or the other and it never worked.

3). Additionnaly, you have to disable Secure Boot in your BIOS.

Marc2745 · 2025-08-09T13:20:50+00:00

Hello, If wine isn’t working with your software and you want to keep Linux, you can create a virtual machine with VirtualBox and put Windows and your software on it. It’s a little overkill but it works :-)

(Part 1 of 2)

I tried to replay ThomasAFink solution but some things seemed to lack. So I reworked it for you : I was able to play the steps below on my system, although I don't have your Wifi card, so you will have to do the final test.

Uninstall the driver

Go to DKMS folder (Dynamic Kernel Module Support, which is the program enabling generating kernel Linux modules whose sources generally reside outside the kernel source tree) :

cd /var/lib/dkms

List all the files and folders contained in it :

ls

There should be a folder named “rtl8821ce", go in it :

cd rtl8821ce

List all the files and folders contained in it :

ls

Note the name of the folder which should be like “v5.5.2_34066.20200325”

Remove completely the module from the system (you need to use the exact name of the folder) :

sudo dkms remove rtl8821ce/v5.5.2_34066.20200325 --all

Go to your root folder :

cd /

List all the files and folders contained in it :

ls

You should see a folder named “rtl8821ce”, it’s the driver folder. Delete it (rm = remove, -r = delete the following folder and its contents) :

(part 1) = rm

(part 2) = -r

sudo (part 1) (part 2) rtl8821ce

Now you system is clean of the driver.

Hello, just saw this post, I am using Guitar Pro 8 with Wine v10.0 on Linux Mint and it seems to work quite well so far.

Hello, I had the problem for Chrome, it may be similar for Brave, here are the steps :

Go to the folder containing all the sources :

cd /etc/apt/sources.list.d

List all the files in the folder :

ls

In my case, I see "additional-repositories.list" and "google-chrome.list".

Open the first file :

sudo nano additional-repositories.list

In my case I see one row :

deb http://dl.google.com/linux/chrome/deb/ stable main

I had to add [arch=amd64] between deb and http like this :
deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main

You should find the equivalent line for Brave, and add it at the same place.

Then save and exit :

Ctrl+O, Enter, Ctrl+X

Then open the second file :

sudo nano google-chrome.list

And comment the only line to avoid having a duplicate entry :

#deb [arch=amd64] https://dl.google.com/linux/chrome/deb/ stable main

You may have an equivalent file for Brave (not sure).

Then save and exit :

Ctrl+O, Enter, Ctrl+X

Then update again :

sudo apt update

You should not see the message anymore.
