Still not sure whether I want to move to Tumbleweed or Gentoo. I have reservations that Gentoo might be less stable but on the other hand you don't have to `emerge --deep @world` every day.

Me considers switching to OpenSuse Tumbleweed.

That's called a dogma then, and no you can't compare gravity to human-made climate change.

> If the Twitter person has real data

His data is the data from the website this HN thread links to.

He's just pointing out that 32% of Sea Surface Temperature (SST) warming since 1995 arrived in a mere 3 weeks of 2023 and asks the question how that is possible.

It's interesting all the responses below here go full ad hominem.

I remember when we first used R in a stochastic class. The professor (a mathematician) was in love with the language and the students (computer science) considered the language to be the PHP of science.

May I ask you what security features you have enabled? Mine looks like this:

I was wondering whether maybe one of those (maybe the kernel lockdown) prevents me from switching the PSR mode?

I'm not sure why it doesn't have an effect on my system. When I add the i915.conf to /etc/modprobe.d/ and reboot my system the PSR is still active:

    [root@fwk ~]# cat /etc/modprobe.d/i915.conf
    options i915 enable_psr=0
    [root@fwk ~]# cat /sys/kernel/debug/dri/1/i915_edp_psr_status
    Sink support: yes [0x03]
    PSR mode: PSR2 enabled
    Source PSR ctl: enabled [0x80000226]
    Source PSR status: SLEEP [0x30000114]
    Busy frontbuffer bits: 0x00000000
    Frame: PSR2 SU blocks:
    0 0
    1 0
    2 0
    3 0
    4 0
    5 0
    6 0
    7 0

It also has no effect when I append i915.enable_psr=0 to GRUB_CMDLINE_LINUX in /etc/default/grub and reboot.

Note that it's a niche product made for people who want to be able to repair and upgrade their hardware. You sound more like you want a Tuxedo InfinityBook or just the new MBP for $4000.

AFAIK you can configure Linux to go from suspend to hibernate after some hours. Hibernate puts the contents of the RAM on disk so it doesn't drain the battery anymore. You can keep a laptop for months in hibernation without losing a lot of battery.

I originally come from a Linux and FreeBSD background. I'm used to having to tweak my OS until everything works and looks and feels the way I want it to be. I started using OS X around ten years ago because I needed things like XCode for work. I like how easy it is to use OS X but at the same time I really despise the closed nature of the OS. What also bugged me is the planned obsolescence of the hardware. My MBP's keyboard started to become awful really quick. Now many keys trigger multiple times and some sometimes not at all. Sometimes I have to type my password five or six times (I'm not a fingerprint guy). What I really like about the Framework laptop is that it is designed to be repairable and upgradeable. I don't want to change my laptop every four or five years if possible. I want to be able to replace its mainboard or the keyboard or the display. I now use the Framework every day for work and I'm not less productive than on OS X. At the same time I believe that all issues will be gone eventually.

Hey @trynewideas! I already tried the i195.enable_psr=0 kernel boot parameter a month ago but it didn't prevent the freezes. Thanks to your input with the i915_edp_psr_status I now found out that the parameter doesn't have any effect on my system. It just doesn't disable PSR. So I tried to regenerate initramfs with dracut, but still got no effect. I then tried to disable PSR via debugfs as root, but for some reason, I can't write to the file:

    [root@fwk ~]# ls -alF /sys/kernel/debug/dri/1/i915_edp_psr_debug
    -rw-r--r--. 1 root root 0 Feb 15 09:09 /sys/kernel/debug/dri/1/i915_edp_psr_debug

    [root@fwk ~]# echo 1 > /sys/kernel/debug/dri/1/i915_edp_psr_debug
    -bash: /sys/kernel/debug/dri/1/i915_edp_psr_debug: Operation not permitted

I'm not sure why I'm unable to write. Do you have to mount debugfs differently to do writes or something like that?

EDIT: debugfs is mounted rw and I tried to disable SELinux temporarily with setenforce 0 but I still can't write.

    [root@fwk ~]# mount | grep  debugfs
    debugfs on /sys/kernel/debug type debugfs (rw,nosuid,nodev,noexec,relatime,seclabel)

    [root@fwk ~]# setenforce 0
    [root@fwk ~]# sestatus | grep Current
    Current mode:                   permissive
    [root@fwk ~]# echo 1 > /sys/kernel/debug/dri/1/i915_edp_psr_debug
    -bash: /sys/kernel/debug/dri/1/i915_edp_psr_debug: Operation not permitted

I also got a kernel update today (6.1.11). According to [the changelog](https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.1.1...) there are a lot of changes regarding the i915 driver but it still freezes on my system.

I'm a developer and I went from using a MBP to a 12th Gen Framework Laptop with Fedora 37. I like the laptop because it has a better keyboard and better battery life than my old MBP (the battery needs repair after 4 years). What I don't like is that it often freezes for 5-10 seconds because of a bug in Intel's i915 driver (GPU Hang). I'm also a bit unhappy about some Linux applications having bad support for fractional scaling. For some reason I can't see the speed of the CPU fan. Looks like there is no sensor for it. Also the display is a bit wobbly, but overall I'm really happy to leave OS X behind and found a way back to Linux. The touchpad isn't as good as the one I'm used to but I have seen worse ones. I hope that you can upgrade it in the future.

EDIT: Oh and the speakers are bad and the mic sometimes doesn't work after waking up from suspend but I read that there's a fix for it.

"It apparently didn't occur to them that if I were a real Japanese spy, I might have brought the glasses with me from headquarters."

I'm not a criminologist but I think they might have classified the glasses and the glasses case and maybe found enough evidence indicating that the glasses have been made in the U.S. or maybe even in San Diego.

Even if they didn't, then it's still their job to do exactly what they did and they were successful. They found the real owner of the glasses and were able to confirm, that the person isn't a potentially dangerous enemy spy. That case can be closed and they can do something else.
