5 Problems starting Tails
6 =======================
8 This section lists known problems with specific hardware. To report a problem
9 with different hardware see our [[report guidelines when Tails does not
10 start|doc/first_steps/bug_reporting/tails_does_not_start]].

14 Problematic USB sticks
15 ----------------------
17 The following USB sticks have issues starting Tails. They are configured by the
18 manufacturer as a fixed disk, and not as a removable disk. As a consequence,
19 they require removing the `live-media=removable` boot parameter, which [[is
20 dangerous|doc/first_steps/bug_reporting/tails_does_not_start#entirely]].
22 * SanDisk Cruzer Edge 8GB
23 * SanDisk Cruzer Extreme USB 3.0 16GB and 32GB
24 * SanDisk Cruzer Fit USB 2.0 8GB, 16GB, and 32G
25 * SanDisk Cruzer Force 8GB
26 * SanDisk Cruzer Glide 4GB, 8GB and 16GB
27 * SanDisk Cruzer Switch USB 2.0 8GB and 32GB
28 * SanDisk Cruzer USB 3.0 64GB
29 * SanDisk Cruzer Blade 4GB and 8GB
30 * SanDisk Cruzer Facet
31 * Staples Relay USB 2.0 16GB
33 SanDisk had begun the production of flash drives configured as fixed disk in
34 2012 to meet new requirements for Windows 8 Certification. The flash drives that
35 comply with this certification will have the Windows 8 logo on their packaging.
36 If a flash drive does not have the Windows 8 logo on its packaging, then that
37 drive will function as a removable disk about should work with Tails.

41 Problematic virtual machines
42 ----------------------------
44 Tails does not work properly when started in a 64-bit QEMU virtual
45 machine with the Cirrus video adapter. One can workaround this problem
46 by using a 32-bit guest CPU, or by using the QXL video
49 See also [[!tails_ticket 7478]].
54 Booting fails with `Not enough memory to load specified image`. Work around by
55 adding the `mem=1500m` [[boot
56 option|/doc/first_steps/startup_options/#boot_menu]].
58 Acer Travelmate 8573T-254G50M
59 -----------------------------
61 Does not start on USB sticks created using Tails Installer.
62 Booting from DVD works fine.
67 For the moment, Tails has a very limited support for Mac.
69 Most recent Mac boot with UEFI only, and currently
70 Tails does not start with UEFI. See [[the corresponding blueprint|blueprint/UEFI]].
72 See also [[manual installation using
73 Mac|doc/first_steps/installation/manual/mac]] for more compatibility
79 Legacy support needs to be enabled in order to start Tails. To enable
80 legacy boot support, enable 'Launch CSM' under boot (menu).
85 You need to update the firmware to its latest version in order to start from a
86 device installed using Tails Installer.
88 Dell Inc. Latitude E6430/0CPWYR
89 -------------------------------
91 Does not start on USB sticks created using Tails Installer.
93 With BIOS versions A03 06/03/2012 (and A09 and A11)
95 Error message: `Invalid partition table!`
97 Workaround (at least with BIOS versions A09 and A11): just hit enter
98 and it will continue with the boot.
100 Dell XPS L702X/03RG89, Samsung RV520, Samsung Series 7 Chronos
101 --------------------------------------------------------------
103 Does not start on USB sticks created using Tails Installer.
105 We were reported that the legacy BIOS shipped on these systems doesn't
106 know how to deal with the GPT partition scheme installed by Tails
109 <http://en.community.dell.com/support-forums/laptop/f/3518/p/19392884/20010995.aspx>
114 The display panel will have the wrong resolution unless `video=LVDS-1:1600x1200
115 nouveau.noaccel=1` is added to the boot command line.
120 Cannot start neither from USB nor from DVD. System crashes with a blank
121 screen and locked up keyboard.
126 With UEFI enabled, when chosing a boot device, select `Boot From EFI File` and
127 then `Filesystem Tails` and `EFI/BOOT/bootx64.efi`.
129 Clevo W258CU, ThinkPad X1, X121e, X220, X230, T420i, T430, T410, T520, W520, T530, E325 and E530
130 ------------------------------------------------------------------------------------------------
132 These machines do not start on USB sticks created using Tails USB
133 Installer, due to a firmware limitation.
135 A workaround for some of these machines is to use the [[manual
136 installation process|doc/first_steps/installation/manual/linux]].
137 Note, however, that this technique does not allow you to set up

143 Fails to start from a Tails USB unless forced to boot using CSM, and not UEFI,
144 first, as advised on:

150 Chainloading Tails from GRUB
151 ----------------------------
153 To workaround problems in booting Tails on laptops with UEFI support, it is
154 possible to chainload the syslinux on the ISO image from another boot loader
155 that is already working on the laptop, like GRUB. Be careful not to modify at
156 all the options of syslinux in the process.
158 The following commands, run from the GRUB shell, might be helpful:
167 Tails might not erase all the system memory on shutdown
168 -------------------------------------------------------
170 On rare systems (non-PAE with big amounts of memory),
171 Tails does not consistently [[!tails_todo
172 more_efficient_memory_wipe desc="erase all system memory as it
175 After using Tails Installer, the "emergency shutdown" doesn't work
176 ------------------------------------------------------------------
178 Tails Installer messes a bit too much with the USB devices for the
179 "emergency shutdown on media removal" feature to continue working after using
180 it. If you believe this feature is critical for the session you're running, we
181 advice you to reboot Tails.
183 Tails DVD eject failure
184 -----------------------
186 Pressing the DVD eject button does not trigger emergency shutdown.
187 Also, the "normal" (non-emergency) shutdown procedure does not eject
190 (Ticket: [[!tails_todo fix_DVD_eject_at_shutdown]])
192 Stream isolation inconsistency in Claws Mail
193 --------------------------------------------
195 Claws Mail isn't using its dedicated Tor SocksPort for Tor hidden
196 service IMAP/POP/SMTP servers (instead Tor's TransPort is used). This
197 is just a deviation from Tails' design and should have no adverse real
200 Tails fails to completely shutdown or restart
201 ---------------------------------------------
203 When stopping Tails on some hardware, the memory wipe procedure fails to
204 complete: the display gets scrambled, but the computer doesn't
205 completely shutdown or restart. Sometimes the caps-lock button light of
206 the keyboard flashes.
208 <div class="caution">
210 When this happens, there is no guarantee that the memory is wiped entirely.
214 This issue has been reported on the following hardware:
216 - Hewlett-Packard HP Pavilion dv6 Notebook PC
217 - Lenovo ThinkPad X61, only on emergency shutdown when pulling out the

233 * Browser window resizing is in not reliable: [[!tails_ticket 6377]]
234 and [[!tor_bug 10095]].
239 Connecting to FTP servers is not possible
240 -----------------------------------------
242 Public FTP servers on the Internet are not reachable using Tails.
243 See [[!tails_todo fix_Internet_FTP_support desc="the corresponding
244 task"]] for more details.
246 YouTube videos are hard to get
247 ------------------------------
249 [[!tails_todo easier_YouTube desc="HTML5 video are not easily seen on YouTube"]]. When the
250 message *This video is currently unavailable* appears, the video can actually be viewed.
251 Right-click on the page, select **NoScript** → **Blocked objects** and
252 **Temporarily allow…** the video.
254 Tails will never support videos which require Flash (those with ads).
256 "Connect automatically" for NetworkManager connections isn't persistent
257 -----------------------------------------------------------------------
259 When the "Network Connections" persistence feature is
260 activated, the "Connect automatically" setting isn't saved for any
261 connection. While this is a bug, it's actually a good
262 one. NetworkManager itself enables this option by default for all new
263 connections, and could result in users re-connecting to a previous network at
264 times when they don't want that.
266 Tails fails to connect to certain Wi-Fi networks
267 ------------------------------------------------
269 This might be related to the introduction of wireless regulation support
272 VirtualBox guest modules are broken for 64-bit guests
273 -----------------------------------------------------
275 VirtualBox guest modules allow for additional features when using Tails as a
276 VirtualBox guest: shared folders, resizable display, shared clipboard, etc.
278 But due to [a bug in VirtualBox](https://www.virtualbox.org/ticket/11037), the
279 resizable display and shared clipboard
280 only work in Tails if the VirtualBox guest is configured to have a 32-bit
281 processor. The shared folders work both on 32-bit and 64-bit guests.
283 Touchpad configurations
284 -----------------------
286 ### Acer TravelMate B113 - ETPS/2 Elantech Touchpad
288 synclient FingerPress=256;
289 synclient TapButton3=0;
290 synclient Clickpad=1;
291 synclient VertTwoFingerScroll=1;
292 synclient FingerLow=1;
293 synclient FingerHigh=1;
295 TorBrowser takes too long to shutdown
296 -------------------------------------
298 Since Tails 0.22, the browser sometimes takes too long to shutdown
299 ([[!tails_ticket 6480]]). Waiting a few more seconds is usually enough
300 to let it close itself correctly.
