1. Analysis of the output of neofetch It appears that you used 'neofetch' to display the available RAM.
According to the source code of neofetch (specifically, the get_memory() function on line 2676), the memory information (3317MiB) is sourced from /proc/meminfo as follows. https://github.com/dylanaraps/neofetch/blob/master/neofetch ```sh $ cat /proc/meminfo | grep "MemTotal" ``` 2. Analysis of the dmesg output ```sh crashkernel reserved: 0x000000007d000000 - 0x000000009d000000 (512 MB) Memory: 3300408K/4105784K available (21788K kernel code, 4575K rwdata, 15820K rodata, 5008K init, 4560K bss, 795668K reserved, 0K cma-reserved) Kernel command line: BOOT_IMAGE=/boot/vmlinuz-6.14.0-33-generic root=UUID=5e941599-5254-42f8-bf32-22057992e495 ro quiet splash crashkernel=2G-4G:320M,4G-32G:512M,32G-64G:1024M,64G-128G:2048M,128G-:4096M vt.handoff=7 ``` If you want to release the 512MB of reserved memory for the crashkernel, you can disable the crashkernel by modifying kernel command line arguments in the /etc/default/grub file. However, keep in mind that doing so may reduce your system's resilience in the event of a crash. So, proceed with caution. Thank you for providing such detailed information to help with the debugging process. ** Changed in: linux (Ubuntu) Status: New => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2127724 Title: Less RAM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2127724/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
