Laptop: open lid and resume.
Server: RAID startup dwarfs OS startup.
Does super fast booting matter much these days? It's just about ceased to matter to me completely.
- acabal 14y agoLinux still has lots of problems with suspend/hibernate/resume on laptops (Oneiric broke hiberanate on my laptop for example), so booting is still kind of important for that reason. Resume from hibernate is another area where I'd like to see improvements. I hibernate instead of suspend because I never know if I'll make it back to an outlet in time.
- javert 14y agoSounds like a problem with Ubuntu, really, not Linux.
- ebiester 14y agoIt's more of a problem with hardware more interested in coding to "works on Windows" than "complies with spec." And honestly, Startup is as fast as resume these days - the problem is applications that don't remember last known state and window managers that won't remember the rest. Why don't we fix that instead rather than chasing down all the suspend bugs?
- mbq 14y agoRestoring app last state? Like terminal emulator recreating tmux session wrapping screen session with package manager working under sudo? SSH unHUP-ing processes on remote machine? Python VM resuming all scripts in a precise place and state they were stopped? The problem is that there is no such thing as isolated "application" on Linux or any other real OS.
- jmah 14y agoRestoring is hard. Let's go shopping!
- javert 14y agoSuspend-to-RAM, as opposed to suspend-to-disk, is way faster than booting. Why chase down suspend bugs? because they are bugs. I'm with you on fixing window managers, generally speaking.
- emmelaich 14y agoI've never had it work reliably with Fedora. Reliable sleep is about the only reason I use Windows now.
- javert 14y agoI definitely could be wrong in my conjecture. I've used sleep reliably under Arch Linux in the past. (Not using it now because my laptop doesn't work anymore without being plugged in.)
- andrewflnr 14y agoOn the same hardware that Ubuntu (and friends) didn't work on? I've been having problems with resuming, and wondered if going to Arch would help, but couldn't think of a real reason why it would.
- LeafStorm 14y agoNewer drivers, for one. Also, it's a lot easier to mess with Arch's internals than Ubuntu's.
- djeikyb 14y agoIt's not a fair test; haven't tried a recent Ubuntu, but: suspend to ram and suspend to disk were broken on Ubuntu 10.04 and 10.10 with my Eeepc 900. Arch + TuxOnIce has worked great for suspend to disk for about a year now.
- rplnt 14y agoI've had some problems with Intel graphics on my DELL in Fedora 14. Sometimes video, sometimes full screen flash, and sometimes sleep caused it to crash. On my older IBM with ATI, everything worked just fine. Anyway, in Fedora 16 the graphics and sleep works just fine for me.
- kleiba 14y agoNote that Ubuntu disables hibernate by default in the current release 12.04 ("Precise Pangolin"). https://wiki.ubuntu.com/PrecisePangolin/ReleaseNotes/UbuntuDesktop#PrecisePangolin.2BAC8-ReleaseNotes.2BAC8-CommonInfrastructure.Common_Infrastructure https://wiki.ubuntu.com/PrecisePangolin/ReleaseNotes/UbuntuD...
- acabal 14y agoWell suspend/hibernate/resume are kernel functions so it is a Linux problem.
- javert 14y agoI'm aware that they're kernel functions, but it's not necessarily that simple.
- kijin 14y agoI try to avoid using sleep/resume when I'm away from home, because it partially defeats the purpose having full-disk encryption on my laptop. A thief who steals it when it's powered off has no access to my files. On the other hand, a thief who steals it when it's asleep might be able to get around the login once it wakes up. So yes, it sucks to wait 30-40 seconds for a reboot.
- idleloops 14y agoWhile I like a fast boot, you've go to get these things a little into perspective, a minute to the desktop isn't that bad.
- Osiris 14y agoBut 20 seconds is even easier. When I switched to an SSD in my laptop I saw boot times from drop almost one minute to just about 15 seconds. I no longer dread having to reboot after system updates.
- DanBC 14y agoIt's not bad, but spread over X million workers on desktops 5 days a week means a lot of wasted time, and maybe energy.
- hmottestad 14y agoIf 5 million people save 1 minute every day for 200 days a year. Then you have saved 1 minute every day per person, not 5 000 000 * 1 * 200 minutes in total per year. That kind of math just doesn't work.
- idleloops 14y agoYeah but you don't have to just sit there and twiddle your thumbs while your machine boots. You can just do something else. I'm sure we waste far more time during the day doing other things. We don't necessarily obsess over those types of time inefficiencies. If you wanted to save time you could brush your teeth in the shower etc.
- hammersend 14y agoAs has been mentioned full disk encryption loses a lot of its efficacy if you just put your laptop in standby all the time. I'd add that as long as a faster boot doesn't compromise your system in other ways, why wouldn't you want it?
- gst 14y agoIt doesn't - if done right. When hibernating my laptop it writes the memory contents into swap - which is also encrypted. Yes, de-hibernating is slower if contents need to be read from disk. OTOH it's still faster than booting from disk.
- hammersend 14y agoI do believe standby and hibernate are different as standby keeps memory contents hot whilst hibernate actually shuts the computer completely down. I was talking about the former in my post above.
- TheBoff 14y agoI this bizarre problem that whenever my fridge turns on, it wakes my laptop from sleep, even if the laptop's not plugged in. The joys of student life!
