Hiya! This isn’t about linux but it does affect me when using linux. Do anyone know how to increase the amount of usable ram in windows? For me my ram is 4GB(2.70GB usable). And overall no matter what linux distro I install it starts being slow after sometime of usage. And even when I’m doing neofetch or htop in linux it’s showing my ram around 2GB which is just sad for me. Even the stock XFCE was slow and sluggish for me Please Reply if anyone knows a fix for this usable ram issue. Also I’m using a DELL inspiron laptop. If you dont know any fixes, kindly recommend me a good looking or themable light distro. Its ok for me even if its a WM distro
Could you please post the exact type of your laptop?
Can you post an output of
sudo lscpu
?
Is there a chance, you installed 32 bit system?
Dell Inspiron Core i5 8th Gen 15.6-inch FHD Laptop (4GB/1TB HDD/Windows 10 Pro) 3576
Can’t speak for Windows, but that laptop should quite fast. It has a much more powerful CPU than mine has, and I don’t experience slowness.
It’s definitely a new and powerful machine, so I have no idea why it’s slow and sluggish for you?
As for RAM amount, let’s check wether you have a 64 bit system?
uname -r
tells your kernel version, if it includes “amd64” then it’s surely 64 bit.
Please show
free -m
to know about memory usage.
The command ps will list processes for you.
ps -aux --sort=%mem
will sort the list by mem usage, the highest will be at the end of the list.
This maybe useful to know, what uses the most memory?
You could install sysstat
sudo apt install sysstat
and then run
iostat -x -t 1
look at %util at the end of the lines of disks.
Is it constantly at a high level (indicates disk bottleneck), or just near zero?
5.4.0-74-generic - This is what uname -r gave
And the last command, its just zero
I may miss something, I expected to have something -i386 -i686 -amd64 at the end of the string.
Something like this:
laco@Z51-70:~$ uname -a
Linux Z51-70 4.19.0-17-amd64 #1 SMP Debian 4.19.194-1 (2021-06-10) x86_64 GNU/Linux
laco@Z51-70:~$ uname -r
4.19.0-17-amd64
What do you get if you run
dpkg -l linux-image*
?

Thanks, its 64 bit.
What about free -m?

Is it possible, that you assigned too much memory in BIOS for the graphics?
idk about that, how do i look it? btw my system is legacy BIOS
Something related to video, shared memory, graphics memory, (probably in an advanced menu in the BIOS), but I can’t tell it exactly without having a very similar device.
I dont have an option like that in my bios setup
At the moment I’m out of ideas, sorry.
Uhm thats alright mate, atleast you tried to help me kudos for that!!
Please, post your full specs with this command: inxi -Fxmz
.
If you do not have it installed, you can install it like this: sudo apt update && sudo apt install -y --install-suggests inxi
I know it seems like you are already using a 64-bit distribution, but this 2.7GB thing strongly suggests some 32-bit limitation.
Here you go…
