Ban Meltdown/Spectre promote CPU performance

A long-time problem has finally been solved ,t440p use chrome I always get stuck badly in meetings , Online search is all about GPU The problem of . It's not , Because Meltdown/Spectre Caused by the patch of CPU Sharp performance degradation . After disabling it, the problem disappears .
Linux The disabling method of is in grub Add ：mitigations=off
Windows have access to inspectre To disable it - https://www.grc.com/inspectre.htm

GPU Accelerate video decoding

Of course , If your GPU Good enough , Hard decoding can also be set , see ： https://my.oschina.net/chipo/blog/3030388
notes ： Refer to the above page to use ‘ppa:saiarcot895/chromium-dev’ After providing some packages , quite a lot desktop All of them opengl Related errors (https://bbs.archlinux.org/viewtopic.php?id=265026), Searched for several days , Finally, it is proved that it has something to do with these packages (vdpauinfo libvdpau-va-gl1 vdpau-driver-all mesa-vdpau-drivers libvdpau1), Delete ppa from ubuntu Just reinstall the official library .

Of my machine GPU no way , Open the Video Decode And pass “–use-gl=desktop“ It will be stuck when starting , But not with –use-gl Starting seems much better （ But open Video Decode).

Test integrated display and independent display

t440p The graphics card ( Centralized display yes HD 4600, Duxian is Nvidia GT730m) How about the performance , Test with the following methods ：

sudo apt-get install glmark2
glmark2 --fullscreen --show-all-options

The result is ：

• nvidia 422 branch - sudo prime-select nvidia
• intel 415 branch - sudo prime-select intel
• Ban nvidia drive 411 branch - rdblacklist=nouveau i965.modeset=1 nouveau.modeset
• There is also a ranking on the Internet - https://technical.city/zh/video/rating?pg=4#result128

upgrade CPU

next step , take t440p Self contained i5-4200M Upgrade to i7-4700mq, There is no change after the upgrade of centralized display or Intel HD Graphics 4600, but cpu Promoted (i7-4700mq The power consumption of 47w, i5-4200M yes 37w, i5-4200M It's two cores and four threads ,7-4700mq It's four cores and eight threads , The maximum frequency is also 3.1 mention 3.4), Theoretically, it should be able to alleviate the problem of cards , see ：https://www.cpubenchmark.net/compare/Intel-i5-4200M-vs-Intel-i7-4700MQ/2016vs1923

Test a series desktop

ubuntu 20.04 The default is gnome 3, but syslog Always see the following errors ：

libinput error: client bug: timer event25 debounce short: scheduled expiry is in the past (-14ms), your system is too slow

Switch to deepin The mistake remains :

Apr  9 19:52:16 t440p com.deepin.daemon.Accounts[2635]: libinput error: client bug: timer event25 debounce short: scheduled expiry is in the past (-14ms), your system is too slow

Then change to ubuntu-budgie But its dock There are always some problems and I don't know how to describe ,
Finally, I switched back to kde, kde At first, I felt great , But it took a day or two to find chrome cpu Also suddenly raised, the fan kept turning for a while, and he recovered , I don't know why .
No desktop is easy to use , Compared with before ubuntu-desktop It's good , So I finally went back to it , But now it also reports the following errors ：

Apr 12 18:08:46 t440p gnome-shell[40666]: Window manager warning: Invalid WM_TRANSIENT_FOR window 0x2c00008 specified for 0x2c00006.
Apr 12 18:08:55 t440p gnome-shell[40666]: message repeated 6 times: [ Window manager warning: Invalid WM_TRANSIENT_FOR window 0x2c00008 specified for 0x2c00006.]

# notes ：ubuntu-appindicators Related errors can be found in gnome-tweak Lieutenant general Ubuntu appindicators Ban , perhaps 
gnome-extensions disable [email protected]

Words , Switching to deepin When I met a pit , I am here ubuntu20.04 Always use hwe newest kernel Of , Switch to deepin The following error was encountered after ：

[email protected]:~$ /usr/bin/deepin-anything-monitor
[2021-04-09, 16:53:33.874] [default-critical] [deepin_anything_server::Server::run: 54]: Failed on open: /proc/vfs_changes "No such file or directory"

This is because hwe The version of is too high to install deepin-anything-dkms Caused by the , So switch back 5.4.0-65 After the kernel is installed successfully with the following methods

sudo add-apt-repository ppa:ubuntudde-dev/stable
sudo apt install ubuntudde-dde -y
sudo dpkg-reconfigure lightdm
sudo apt remove startdde ubuntudde-dde

deb [by-hash=force] http://packages.deepin.com/deepin lion main contrib non-free

sudo apt install deepin-anything-server deepin-anything-server-dev deepin-anything-libs deepin-anything-dkms deepin-anything-dev -y
sudo apt reinstall deepin-anything-dkms

install KDE

sudo apt install kubuntu-desktop kde-standard

install Ubuntu desktop, And use gnome-tweaks Set up ubuntu dock To always show

sudo apt install --reinstall ubuntu-desktop

ubuntu desktop There is no load to report the following problems , Is it cpu It's time to clear the dust ？

Apr 10 08:26:37 t440p kernel: [37334.508417] mce: CPU1: Core temperature above threshold, cpu clock throttled (total events = 36350)
Apr 10 08:26:37 t440p kernel: [37334.508420] mce: CPU0: Core temperature above threshold, cpu clock throttled (total events = 36348)

install gnome 3

sudo apt install gnome-session gdm3 -y

install ubuntu-budgie

sudo apt install ubuntu-budgie-desktop
#sudo apt remove ubuntu-budgie-desktop ubuntu-budgie* lightdm
#sudo apt autoremove
#sudo apt install --reinstall gdm3

It may be smoother manjaro kde, I don't want to reload , give up ！

summary

How to have a smooth ubuntu Office environment ：

• GPU Acceleration is on , upgrade chrome Up to date 89 edition , There is that in this patch, So don't use ppa:saiarcot895/chromium-dev
• Use mitigations=off, And from i5 Upgrade to i7
• Use gnome, Don't use kde, ubuntu desktop, deepin Other desktop , Try it or gnome It is best to
• Use wayland Don't use xorg, Because there are two monitors used wayland Support sharing only a single screen ( notes ：wayland still bug Too much , Sharing a single screen is black )
• Use lightdm Don't use gdm, because wayland+gdm3 The combination will result in chrome When copying often hang There , In addition, use gdm3 stay t440p It often happens on login loop The problem of （ On the desktop, because of a problem, you can only use gdm3, I forgot something )
• Ban gnome ubuntu-appindicators plugin, This plug-in is in syslog There are too many mistakes in the report .gnome-extensions disable [email protected]
• gedit Support recently opened files - gsettings set org.gnome.desktop.privacy remember-recent-files true
• Set Microsoft fonts

sudo apt-get install --reinstall ttf-mscorefonts-installer
sudo apt-get install xfonts-wqy     # WenQuanYi - Dot matrix Tahoma 
sudo apt-get install ttf-wqy*kk     # WenQuanYi is in the dark 
sudo fc-cache -f -s -v   # Refresh font cache 
#  open gnome-tweak by gnome desktop Choose to use WenQuanYi constant width font 
sudo apt-get install gnome-tweak-tool font-manager gnome-tweak
#  Also in the chrome Search in settings “ typeface ” by chrome Set Microsoft fonts 
#  Or use Stylish Set font to Microsoft YaHei,  see ：https://blog.csdn.net/pyufftj/article/details/80712303

• Install some gnome plugin, And in gnome-tweak Plug in for , And install the lunar calendar plug-in

sudo apt install gnome-shell-extensions
sudo apt install chrome-gnome-shell
 Install dependency first （apt install gir1.2-lunar-date-2.0）, Then install the lunar calendar plug-in https://extensions.gnome.org/extension/675/lunar-calendar/ , Finally, you need to set ubuntu The language is Chinese, and the agricultural pressure display will not be garbled .
