 Posted: Mon Jun 27, 2022 9:06 pm Post subject: [SOLVED] Revert changes to kernel config? |
 |
|
Hello!
I used make menuconfig to edit and prepare my kernel for xorg and proprietary nvidia. However, I realised shortly after that since I used genkernel to set up my kernel, I didn’t need to edit it.
Is there an easy way to revert the changes I’ve done to the config? I’ve saved the changes but I haven’t compiled it yet, so can I replace the edited config with the unedited one that’s currently active?
I’d appreciate your help command by command, as I’m new. Thanks!

Try
| Code: |
zcat /proc/config.gz > /usr/src/linux/.config

Hi, ceramide,
Welcome to gentoo.
I dunno nothing about genkernel...
Still, in the kernel directory from where you launched 'make menuconfig', you could launch: | Code: | amd64 /usr/src/linux-5.15.43-gentoo-r8168 # ls -la .config*
-rw-r--r-- 1 root root 115528 mai 29 04:02 .config
-rw-r--r-- 1 root root 115339 mai 14 16:47 .config.old |
You could investigate a little further with | Code: | | amd64 /usr/src/linux-5.15.43-gentoo-r8168 # diff .config .config.old |
Thks 4 ur attention, interest & support.

Hi
As CaptainBlood wrote , If you like gekernel tool I suggest following
genkernel and its options to save and recall your various config (or test config)
Basically I run
| Code: |
Make a copy of running kernel config ;
# zcat /proc/config.gz > /etc/kernels/my_running_config
# genkernel --save-config --kernel-config=/your/custom/kernel/config_file --install --menuconfig all
|
No need to run --menuconfig when then kernel config is not edited
By default genkernel save the config in /etc/kernels directory when --save-config is used ,
See genkernel manual

| Solved. Thanks everyone for the help and advice. I used the command posted by alamahant to “reset” the kernel config. |
