Some problems and solutions that you encounter with Linux

1. How to continue using previously used Thunderbird mail after reloading the system or changing the machine

Executing the command Thunderbird-profilemanager will open a configuration user interface later.

Add a new configuration inside, and then select the directory where the message was previously stored: for example .../mails/archievemails/

There should be a number of similar configuration files:

ls /mydisk/other/mymails/blist.sqlite        foldertree.json            places.sqlite-Walcache               Global-messages-db.sqlite  prefs.js_cache_clean_       key3.db                    secmod.dbcert8.db            LOCALSTORE.RDF             Startupcachecompatibility.ini   lock                       times.jsoncookies.sqlite      MailViews.dat              virtualFolders.datcookies.sqlite-shm  minidumps                  webappsstore.sqlitecookies.sqlite -wal  permissions.sqlite         webappsstore.sqlite-shmextensions.ini      places.sqlite              Webappsstore.sqlite-walextensions.sqlite   places.sqlite-SHM

Be sure to use this configuration to continue using the previous message.

Tip: If it is a dual system, it can be configured in the same directory, so that the message will not be repeated, which system is the same use.

2. Direct use of the ISO installation system

A. Place the ISO in a EXT3/4-formatted partition, remembering the partition number, such as/dev/sda3

B. Restart the system to enter the grub interface, press ' C ' to enter the command editing interface

C. Enter:

Set root=/path/to/iso , msdos2 as root directory Linux (LO)/images/pxeboot/vmlinuz Linux repo=hd:/dev/sda:/ path/to/isoinitrd (lo)/images/pxeboot/initrd.imgboot

This allows the installation to start directly from ISO without the need for an optical drive.

(Prerequisite: Grub2 above the function, the system partition is the best ext, it seems that NTFS startup problems)

3.samba use prompt: Failed to find the entry to XXX

Cause: You need to add the current user to the Samba users list

Execute the following command:

# smbpasswd-a Fyu (Fyu for an already existing user, can use the current user directly)

4. Modify Gnome's parameter settings

Gsettings Set Org.gnome.desktop.interface toolkit-accessibility True

5. Binding and Unbinding drivers

A. First find the corresponding driving position, for example, for the network card, may be/sys/bus/pci/drivers/igb/

Then find the ID number you want to bind the driver to:

# lspci-nnd

0000:02:00.0 Ethernet Controller [0200]: Marvell Technology Group Ltd. 88E8057 PCI-E Gigabit Ethernet Controller [11ab:438 0] (Rev 10)
0000:03:04.0 Ethernet Controller [0200]: Realtek Semiconductor Co., Ltd. RTL8169 PCI Gigabit Ethernet Controller [10ec:816 9] (Rev 10)

B. Binding: (Device:vender refers to a set of numbers inside a box)

# echo-n 10ec 8169 >/sys/bus/pci/drivers/igb/new_id

C. Unbind: (ID number refers to the first group number: domain:bus:slot.function) # echo-n 0000:03:04.0 >/sys/bus/pci/drivers/igb/unbind

Or:

# echo-n 0000:03:04.0 >/sys/bus/pci/devices/0000:03:04.0/drivers/unbind
