comment Performance issues on Lenovo T460s (seems like graphics problem under metacity)
Ok, so I tried the advice I'd seen elsewhere - removing the Intel driver and thus falling back on the modesetting driver built into Xorg. Upside : the YouTube "fade" transition is much faster. Something has changed. It is still, however, not smooth or fast. Downside : Not sure if this just because I restarted a browser session with about 30 windows in it shortly after removing the driver and rebooting, but it provoked the first time this laptop has actually built up enough heat to start the fan. Going to try this out for a while to see if this is a general trend.

A good test of this is pressing the "full screen" button on a YouTube video - the fancy fade that it does is very, very slow - it's several seconds before the video shows up full screen, and also several seconds lag occur between moving the mouse and the video controls appearing on screen. It seems like anything involving a "fade" is very very slow - including the fade out when you close a detail view of a tweet on the Twitter web app.

The most recent kernel fixes the "close the lid and it crashes" bug that the no_hwp line worked around - but does this have any other impact on the performance problem mentioned?

comment Is it possible to connect to multiple VPN networks at once via Network Manager?
I think this only works if the VPN connections use different providers. e.g. not both Cisco vpnc connctions. I've even had cases where VPN using a given provider just broke and refused to reconnect until I rebooted when I tried this.

comment How can I dual-boot Windows 10 and Ubuntu on a UEFI HP notebook?
You must mark the boot partition with the boot + esp flags using gparted as well ; I didn't do this and Windows refused to share a disk with Ubuntu (which installed in legacy boot mode). Once you mark a partition with these flags the Ubuntu installer will automatically use it and install in EFI mode. And then Windows won't refuse to install on the same disk with the error "couldn't create a new partition"..

comment How can I make Deja Dup use AES 256 as the encryption algorithm?
Not sure this is accurate - from the manual, s2k-cipher-algo is used for encrypting private keys, whereas just plain "cipher-algo" determines the symmetric algorithm. (and the default is Blowfish) gnupg.org/gph/en/manual/r1434.html

comment How to install Ubuntu with both disk encryption AND SSD caching
I can't really claim to know - but I'm guessing it might be a side-effect of the optimizations involved in minimizing writes to the SSD. Article about IOWait here : thattommyhall.com/2011/02/18/iops-linux-iostat

comment Is stopping Ubuntu at HP Compaq PC by pressing shortly the computer power button OK?
It doesn't sound like the button you are pushing is really the "reset" button. From the behaviour you're getting, it's the ACPI power button. The real "reset" button is usually much smaller and sometimes recessed a little in the case to make it harder to push - because it really does just reset things without prompting. The fact that you're getting a prompt means you're pushing the power button. Shutting down this way is completely fine - it really is just like using the "Shut Down" menu. For the "real" reset button, see the other question linked here.
