I have installed and tested Enlightenment in an Lubuntu 20.04.5 with Kernel 6.0. The Enlightenment version (2019) is from Ubuntu repository. Not using the current up to date version.
Comparing between Enlightenment and LXQT :
- With Enlightenment the total OS RAM was less than 50 MB.
- Same 3D peformance between Enlightenment and LXQT.
- Enlightenment is more fast to start and others tasks related with window.
Really is very fast.
Enlightenment have much more options to tweak than LXQT and is more complex to configure.
Having conflicts with some others softwares and the menu are much little.
In moment not configured all options.
About “glmark2” score from 7392 and LxQt desktop to 9842.
Which are the tests used ?
glmark2 is an test in Phoronix Test Suite ?
I use Linux since 2020 at moment I not known one software allowing configure GTK settings.
GTK has an terrible problem with “pop up messages” because have few detaly to show it and even has an bug doing the pop up message window to be for an long time thus need move the mouse pointer over the same area where was done the “pop up message” to close it.
About flatpak I never had used any flatpak software.
I had tested one time to download an software. I not remember if was flatpak or snap.
The same software being download in deb file format was less than 20 MB.
Thus I had selected to download that software. Time passing and more than 350 MB downloaded an not any progress in software download percentage. I had canceled.
I use browsers Seamonkey and Waterfox in tar format.
After extract in /opt in an program folder being owner the username.
Seamonkey use much less RAM than Firefox even using some addons (Cookies Exterminator, Noscript and Ad Block).
Seamonkey was created by Netscape Navigator coders.
However has some problems not being exactly related with Seamonkey code.
Some sites are created with scripts to allow access to an list of browsers and Seamonkey not was added.
Thus the site not work correctly and in some sites is showed message to change or update the browser.
Here even not is possible login using Seamonkey, but using User Agent Switcher “fix” it.
In moment in my Seamonkey access experience the only problem is in Github.
Some links have in download area an “Asset” menu doing an animation scrolling an list of file to download. Seamonkey not show the list even if using User Agent Switcher.
That’s the because I have also Waterfox only for Github and other security sites.
Now in moment Lubuntu 20.04.5 Kernel 6 + file manager + Kate + Cherrytree + Seamonkey opened browser and mail windows + smplayer the total RAM is 1,36 even using tmpfs and Seamonkey using /tmp to temporary files.
My cousin have an notebook 2010 intel pentium dual core 2 GB … had “other OS 10” … OS loaded using more than 1,5 GB RAM … after of some updates several minutes to boot and almost impossible to run Firefox because of high slowdown. All time having disk access read and write (swap) ! Terrible.
Thus I had installed Lubuntu 20.04.5.
Now is as if using an “new” notebook.
Disk partitioned using GPT table using partitions.
1 = 8 MB unformatted for BIOS GRUB
2 = 600 MB ext2 for /boot
3 = 20 GB BTRFS for /
4 = 2 GB BTRFS for /home
5 = Using the total free disk space BTRFS for /opt
BTRFS using compress-force zlib:9 … much less written access in disk thus doing fast disk access. File I/O have better performance using BTRFS.
/opt for all softwares not installed using apt and also others type of software and data. Thus not need format /opt when re installing the OS.
Enabled zram 512 MB and tmpfs.
Now that notebook run softwares with much more performance speed.
Seamonkey and Firefox use the same settings.
Thus was disabled memory (ram) cache. Not disable disk cache and configure to use /tmp to temporary folder.
Using about:config
Browser.cache.memory.enable = false
Browser.cache.disk.enable = true
browser.cache.disk.parent_directory = string value > /tmp
browser.cache.disk.capacity = integer value > 262144 ( 256 MB)
Only avoid open much tabs at same time.
Have another distros using less RAM. LXDE use less RAM perhaps less than Enligthment.
I had done an search about it and trying see if is possible add any component to Lubuntu optimizing the RAM usage.
My experience searching was has few distros using less RAM, but not are exactly privacy secure.
Have an distro using less of 256 MB automatically creating favorites bookmarks to browsers about politics. The user remove and after the link return. The team is “anti” politics.
When changing from "other OS’ to Linux my choice was Ubuntu because is “more simple” to tweak and find softwares. High number of compiled softwares for Ubuntu.
I will continue using Lubuntu. Unhappiy LXQT have problems not allowing configure menu links.
MenuLibre is an solution. However the software has an bug allowing to be used only one time and after all options to configure links are missing.
I remember trying install Lubuntu 20.04 in an Phenom X4. The problem was the IGP Geforce 6100. The screen had problems with colors being rendered wrong colors in SDDM login (almost all using black color). The IGP was configured to use more than 64 MB.
In other hand if the video card or IGP run correctly will have much better performance and features than if using “other OS”.
An long reply. I want share some informations and experiences.
