<p>It's possible that your graphs won't look great out of the box due to the reliance on braille fonts to draw them. One
example of this is seeing a bunch of missing font characters, caused when the terminal isn't configured properly to
render braille fonts.</p>
<figure>
<img src="../assets/screenshots/troubleshooting/no_braille.webp" alt="Example of a terminal with no braille font."/>
<figcaption><sub>An example of missing braille fonts in Powershell</sub></figcaption>
</figure>
<p>One alternative is to use the <code>--dot_marker</code> option to render graph charts using dots instead of the braille characters,
which generally seems better supported out of the box, at the expense of looking less intricate:</p>
<figure>
<img src="../assets/screenshots/troubleshooting/dots.webp" alt="Example of running bottom with the dot marker flag"/>
<figcaption><sub>Example using <code>btm --dot_marker</code></sub></figcaption>
</figure>
<p>Another (better) alternative is to install a font that supports braille fonts, and configure your terminal emulator to use it.
For example, installing something like <a href="https://yudit.org/download/fonts/UBraille/">UBraille</a> or <a href="https://github.com/be5invis/Iosevka">Iosevka</a>
and ensuring your terminal uses it should work.</p>
<h3 id="braille-font-issues-on-linuxmacosunix-like"><a class="toclink" href="#braille-font-issues-on-linuxmacosunix-like">Braille font issues on Linux/macOS/Unix-like</a></h3>
<p>Generally, the problem comes down to you either not having a font that supports the braille markers, or your terminal
emulator is not using the correct font for the braille markers.</p>
<p>See <a href="https://github.com/cjbassi/gotop/issues/18">here</a> for possible fixes if you're having font issues on Linux, which
may also be helpful for macOS or other Unix-like systems.</p>
<p>If you're still having issues, feel free to open a <a href="https://github.com/ClementTsang/bottom/discussions/new/">discussion</a>
question about it.</p>

<p><strong>Note: I would advise backing up your registry beforehand if you aren't sure what you are doing!</strong></p>
<p>Let's say you're installing <a href="https://github.com/be5invis/Iosevka">Iosevka</a>. The steps you can take are:</p>
<ol>
<li>Install the font itself.</li>
<li>Open the registry editor, which you can do either by <code>Win+R</code> and opening <code>regedit</code>, or just opening it from the Start Menu.</li>
<li>
<p>In the registry editor, go to</p>
<div class="highlight"><pre><span></span><code>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont
</code></pre></div>
</li>
<li>
<p>Here, add a new <code>String value</code>, and set the <code>Name</code> to a bunch of 0's (e.g. <code>000</code> - make sure the name isn't already used), then set the <code>Data</code> to the font name (e.g. <code>Iosevka</code>).</p>
</li>
</ol>
<figure>
<img src="../assets/screenshots/troubleshooting/regedit_fonts.webp" alt="Regedit menu showing how to add a new font for Command Prompt/PowerShell"/>
<figcaption><sub>The last entry is the new entry for Iosevka</sub></figcaption>
</figure>
<ol>
<li>Then, open the Command Prompt/PowerShell, and right click on the top bar, and open "Properties":</li>
</ol>
<figure>
<img src="../assets/screenshots/troubleshooting/cmd_prompt_props.webp" alt="Opening the properties menu in Command Prompt/PowerShell"/>
</figure>
<ol>
<li>From here, go to "Font", and set the font to your new font (so in this example, Iosevka):</li>
</ol>

<p>This is a <a href="../support/official/#windows">known limitation</a>, some sensors may require admin privileges to get sensor data.</p>
<h2 id="why-dont-i-see-dual-batteries-on-windows-reported-separately-eg-thinkpads"><a class="toclink" href="#why-dont-i-see-dual-batteries-on-windows-reported-separately-eg-thinkpads">Why don't I see dual batteries on Windows reported separately? (e.g. Thinkpads)</a></h2>
<p>This is a <a href="../support/official/#windows">known limitation</a> which seems to be with how batteries are being detected on Windows.</p>
<h2 id="why-cant-i-see-all-my-temperature-sensors-on-wsl"><a class="toclink" href="#why-cant-i-see-all-my-temperature-sensors-on-wsl">Why can't I see all my temperature sensors on WSL?</a></h2>
<p>This is a <a href="../support/official/#windows">known limitation</a> with WSL. Due to how it works, hosts may not expose their
temperature sensors and therefore, temperature sensors might be missing.</p>
<h2 id="why-does-wsl2-not-match-task-manager"><a class="toclink" href="#why-does-wsl2-not-match-task-manager">Why does WSL2 not match Task Manager?</a></h2>
<p>This is a <a href="../support/official/#windows">known limitation</a> with WSL2. Due to how WSL2 works, the two might not match
up in terms of reported data.</p>
<h2 id="why-cant-i-see-all-my-processesprocess-data-on-macos"><a class="toclink" href="#why-cant-i-see-all-my-processesprocess-data-on-macos">Why can't I see all my processes/process data on macOS?</a></h2>
<p>This is a <a href="../support/official/#macos">known limitation</a>, and you may have to run the program with elevated
privileges to work around it - for example:</p>
<div class="highlight"><pre><span></span><code>sudo<span class="w"> </span>btm
</code></pre></div>
<p><strong>Please note that you should be certain that you trust any software you grant root privileges.</strong></p>
<p>There are measures taken to try to maximize the amount of information obtained without elevated privileges. For example,
one can modify the instructions found on the <a href="https://github.com/hishamhm/htop/wiki/macOS:-run-without-sudo">htop wiki</a>
on how to run htop without sudo for bottom. However <strong>please</strong> understand the potential security risks before doing so!</p>
<h2 id="my-configuration-file-isnt-working"><a class="toclink" href="#my-configuration-file-isnt-working">My configuration file isn't working</a></h2>
<p>If your configuration files aren't working, here are a few things to try:</p>
<h3 id="check-the-formatting"><a class="toclink" href="#check-the-formatting">Check the formatting</a></h3>
<p>It may be handy to refer to the automatically generated config files or the <a href="https://github.com/ClementTsang/bottom/tree/master/sample_configs">sample configuration files</a>.
The config files also follow the <a href="https://toml.io/en/">TOML</a> format.</p>
<p>Also make sure your config options are under the right table - for example, to set your temperature type, you must set it under the <code>[flags]</code> table:</p>
<div class="highlight"><pre><span></span><code><span class="k">[flags]</span>
<span class="n">temperature_type</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="s">&quot;f&quot;</span>
</code></pre></div>
<p>Meanwhile, if you want to set a custom color scheme, it would be under the <code>[colors]</code> table:</p>
<div class="highlight"><pre><span></span><code><span class="k">[colors]</span>
<span class="n">table_header_color</span><span class="o">=</span><span class="s">&quot;LightBlue&quot;</span>
</code></pre></div>
<h3 id="check-the-configuration-file-location"><a class="toclink" href="#check-the-configuration-file-location">Check the configuration file location</a></h3>
<p>Make sure bottom is reading the right configuration file. By default, bottom looks for config files at these locations:</p>
<table>
<thead>
<tr>
<th>OS</th>
<th>Default Config Location</th>
</tr>
</thead>
<tbody>
<tr>
<td>macOS</td>
<td><code>$HOME/Library/Application Support/bottom/bottom.toml</code><br/> <code>~/.config/bottom/bottom.toml</code> <br/> <code>$XDG_CONFIG_HOME/bottom/bottom.toml</code></td>
</tr>
<tr>
<td>Linux</td>
<td><code>~/.config/bottom/bottom.toml</code> <br/> <code>$XDG_CONFIG_HOME/bottom/bottom.toml</code></td>
</tr>
<tr>
<td>Windows</td>
<td><code>C:\Users\&lt;USER&gt;\AppData\Roaming\bottom\bottom.toml</code></td>
</tr>
</tbody>
</table>
<p>If you want to use a config file in another location, use the <code>--config</code> or <code>-C</code> flags along with the path to the configuration file, like so:</p>
<div class="highlight"><pre><span></span><code>btm<span class="w"> </span>-C<span class="w"> </span>path_to_config
</code></pre></div>
<h2 id="my-installation-through-snap-has-some-widgets-that-are-blankshow-no-data"><a class="toclink" href="#my-installation-through-snap-has-some-widgets-that-are-blankshow-no-data">My installation through snap has some widgets that are blank/show no data</a></h2>
<p>Make sure bottom is given the correct permissions in order to collect data. <a href="https://snapcraft.io/docs/interface-management">Snapcraft</a>
explains how to do so, but the TL;DR is:</p>
<div class="highlight"><pre><span></span><code>sudo<span class="w"> </span>snap<span class="w"> </span>connect<span class="w"> </span>bottom:mount-observe
sudo<span class="w"> </span>snap<span class="w"> </span>connect<span class="w"> </span>bottom:hardware-observe
sudo<span class="w"> </span>snap<span class="w"> </span>connect<span class="w"> </span>bottom:system-observe
sudo<span class="w"> </span>snap<span class="w"> </span>connect<span class="w"> </span>bottom:process-control
</code></pre></div>
